The ATD control register 5 is used to select the conversion modes, the conversion channel(s), and ini-
tiate conversions.
Read or write anytime. Writes to the ATD control registers initiate a new conversion sequence. If a con-
version sequence is in progress when a write occurs, that sequence is aborted and the SCF and CCF
bits are reset.
S8CM — Select 8 Channel Mode
0 = Conversion sequence consists of four conversions
1 = Conversion sequence consists of eight conversions
SCAN — Enable Continuous Channel Scan
0 = Single conversion sequence
1 = Continuous conversion sequences (scan mode)
When a conversion sequence is initiated by a write to the ATDCTL register, the user has a choice of
performing a sequence of four (or eight, depending on the S8CM bit) conversions or continuously per-
forming four (or eight) conversion sequences.
MULT — Enable Multichannel Conversion
0 = ATD sequencer runs all four or eight conversions on a
single
input channel selected via the
CD, CC, CB, and CA bits.
1 = ATD sequencer runs each of the four or eight conversions on
sequential
channels in a specific
group. Refer to
Table 41
.
CD, CC, CB, and CA — Channel Select for Conversion
NOTES:
1. Maximum conversion frequency is 2 MHz. Maximum P clock divisor value will become
maximum conversion rate that can be used on this ATD module.
2. Minimum conversion frequency is 500 kHz. Minimum P clock divisor value will become
minimum conversion rate that this ATD can perform.
