DSAD (bit 0)
The DSAD bit is used to control SA type A/D converter operation. When the DSAD bit is set to “1”, the circuits
related to SA type A/D converter are reset and turned off.
DSAD Description
0 Enable operating SA type A/D converter (initial value)
1
Disable operating SA type A/D converter
Note:
When certain bits of block control registers are set to “1”, corresponding peripherals are reset (all registers are reset) and
operating clocks for the peripherals stop. Writing to every SFR (special function register) in the corresponding
peripherals is not valid while the bits of block control registers are set to “1” and returns the initial value for read.
Ensure the bits are reset to “0” before using the peripherals to enable the operation.
