Product Overview Address Spaces Addressing Modes Control Registers Interrupt Structure Instruction Set KS88C8424/C8432/P8432 PRODUCT OVERVIEW 1 PRODUCT OVERVIEW SAM87 PRODUCT FAMILY Samsung's SAM87 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various mask-programmable ROM sizes. Important CPU features include: — Efficient register-oriented architecture — Selectable CPU clock sources — Release of Idle and Stop power-down modes by interrupt — Built-in basic timer circuit with watchdog function A sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more interrupt sources and vectors. Fast interrupt processing (within a minimum of six CPU clocks) can be assigned to specific interrupt levels. KS88C8424/C8432/P8432 MICROCONTROLLERS The KS88C8424 microcontroller has a 24-Kbyte on-chip program memory and the KS88C8432 has a 32-Kbyte. Both chips have a 272-byte general-purpose internal register file. The interrupt structure has nine interrupt sources with nine interrupt vectors. The CPU recognizes seven interrupt priority levels. Using a modular design approach, the following peripherals were integrated with the SAM87 core to make the KS88C8424/C8432/P8432 microcontrollers suitable for use in color television and other types of screen display applications: — Four programmable I/O ports (26 pins total: 16 general-purpose I/O pins; 10 n-channel, open-d...
