TEL: (03) 5639977 FAX: (03) 5630118 Version History Specification Revision History Version EM78P569 3.7 3.8 3.9 4.0 Content Modify Multiplier function 1. Move DARES bit from bit7 to bit3. 2. Change instruction “MUL” “INT A” 1. Update Application Note 2. Add 17.91MHz main CLK 1. Add data RAM address auto-increase function 2. Add mclk/2 signal output. (output shared with PC0) 3. Add carry bit calculation function.(ADD, SUB) Modify the relative between VERSEL (code option) and PLUS (RA page2) Modify code option define. Add the OSC stable and reset timing diagram Remove IDLE mode Modify operating temperature 4.1 4.2 4.3 4.4 User Application Note (Before using this chip, take a look at the following description note, it includes important messages.) 1. There are some undefined bits in the registers. The values in these bits are unpredicted. These bits are not allowed to use. We use the symbol “-” in the spec to recognize them. 2. You will see some names for the register bits definitions. Some name will be appear very frequently in the whole spec. The following describes the meaning for the register’s definitions such as bit type, bit name, bit number and so on. RA PAGE0 7 RAB7 R/W -0 Bit type Bit name Bit number Register name and its page 6 RAB6 R/W -0 read/write (default value=0) 5 BAB5 R-1 4 RAB4 R/W -1 read/write (default value=1) 3 - 2 RAB2 R 1 RAB1 R-0 0 RAB0 R/W read/write (w/o default value) read only (w/o default value) (undefined) not allowed to use read only (default value=1) read only (default value=0) 3. Always set IOCC PAGE1 bit 1 = 1 otherwise partial ADC function cannot be used. For 8 bits resolution DAC, DAO pin will output corresponding voltage after write new data to DAC data buffer(RA PAGE1). For 10 bits resolution, DAO pin will output constant after change DAC most significant 2 bits (R5 PAGE1 bit6~7). DAO will output correct voltage after write data to least significant 8 bits. That is to say, when using 10 bits resolution DAC, user must write most significant 2 bits and least significant 8 bits in order. 5. Base on “VERSEL”(code option) equal 0 or 1, R8 page1 and RB page2’s define are different. “VERSEL” = 0: R8 page1 defined to data RAM address buffer RB page2 defined to multiplier’s Y data or Y address buffer (controlled by RA page2 bit5 “INDR”). RA page2 bit4(PLUS) determine RAM address auto increase or not (only for multiplier’s addressing). RA page2 bit7 is undefined. “VERSEL” = 1: R8 page1 is undefined. RA page2 bit4(PLUS) determine RAM address auto increase or not (for data RAM and multiplier’s addressing). RA page2 bit7(INS) determine . RB page2 defined to multiplier’s Y data, Y address or data RAM address buffer. 6. The carry bit’s initial value is un-know, please define the initial value before execute first ADD or SUB instruction that include carry bit.(VERSEL =1 and INS = 1) 7. In EM78569’s developing tool, “VERSEL” and “PHO” are at RD page2 bit6 and bit5, but in mask chip, these two bits will mapping to code option. Please set these two bits to fixed value at initial and do not change these two bit among your program. 4. The differences between ICE569, EM78P569 and EM78569. Stack ICE569 16 EM78P569 16 EM78569 12 EM78P569 8-bit OTP Micro-controller I. General Description The EM78P569 is an 8-bit RISC type microprocessor with low power, high speed CMOS technology. There are 16Kx13 bits Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides security bits and some One time programmable Option bits to protect the OTP memory code from any external access as well as to meet user’s options. This integrated single chip has an on_chip watchdog timer (WDT), program OTP-ROM, data RAM, LCD driver, programmable real time clock/counter, internal interrupt, power down mode, built-in three-wire SPI, dual PWM(Pulse Width Modulation), 6-channel 10-bit A/D converter, 10-bit D/A converter and tri-state I/O.
