FRZ1, FRZ0 — Background Debug Freeze Enable
ATD control register 4 is used to select the internal ATD clock frequency
(based on the system clock), select the length of the third phase of the
sample period, and set the resolution of the A/D conversion (i.e. 8-bits or
10-bits). 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 ATDCTL5) initiates a new conversion sequence.
Finally, which result registers hold valid data can be tracked using the
conversion complete flags. Fast flag clear mode may or may not be
useful in a particular application to track valid data.
Background debug freeze function allows the ATD module to pause
when a breakpoint is encountered.
FRZ0 determine the ATD’s response to a breakpoint. When BDM is
deasserted, the ATD module continues operating as it was before the
breakpoint occurred.
