The asterisk can be either 0 or 1.

Conversion time is for fCLK = 32.768kHz.

These mode setting bits (bit 0 and bits 3 to 5) are common for each channel, the last setting of bits (bit0 and bits3 to 5) is

effective for all channels. Furthermore, bits 1 and 2 are independent and can be set for each channel.

Note: These parameters are reference values derived through calculations and are not guaranteed characteristic values.
