ATD control register 5 determines the type of conversion sequence and
the analog input channels sampled. All writes to this register have an
immediate effect. If a conversion is in progress, the entire conversion
sequence is aborted. A write to this register (or ATDCTL4) initiates a new
conversion sequence (SCF and CCF bits are reset).
S8C / S1C — Conversion Sequence Length
1. Maximum conversion frequency is 2 MHz. Maximum PCLK divisor value will become
2. Minimum conversion frequency is 500 kHz. Minimum PCLK divisor value will become
S8C: Bit Position: 6, ATDCTL5
S1C: Bit Position: 3, ATDCTL3
The S8C/S1C bits define the length of a conversion sequence.
