(AN0 to AN3) can be used as general-purpose digital inputs (Port 5) if not needed as analog
channels.
The TMP91CW40 has a 10-bit successive-approximation analog-to-digital converter (AD
Figure 3.16.1 shows a block diagram of the AD converter. The four analog input channels
Ensure that the AD converter has halted before executing the HALT instruction to place the TMP91CW40 in IDLE2,
IDLE1 or STOP mode to reduce power supply current. Otherwise, the TMP91CW40 might go into a standby mode
while the internal analog comparator is still active.
