While switching main clock (regardless of high freq to low freq or on the other hand), adding 6 instructions delay (NOP) is required. 4. RE page1 Bit6~Bit7 are Un-defined registers. These two bits are un-define and their values will variation. During calculation, please do not include these two bits. 5. Please do not switch MCU operation mode from normal mode to sleep mode directly. Before into idle or sleep mode, please switch MCU to green mode. 6. Please always keep RA page0 bit7 = 0 or un-expect error will happen!! EM78P870 8-bit OTP Micro-co...
