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. A fixed value
must be write in some specific unused bits by software or some unpredicted wrong will occur.

These bits are as below.

3. Always set IOCC PAGE1 bit 0 = 1 otherwise partial ADC function cannot be used.

4. Please do not switch MCU operation mode from normal mode to sleep mode directly. Before

into sleep mode, please switch MCU to green mode.

5. While switching main clock (regardless of high freq to low freq or on the other hand), adding 6

instructions delay (NOP) is required.

6. Offset voltage will effect ADC

s result, please refer to figure 16 to detail.
