If the ASWAI control bit in ATDCTL2 is set, then the ATD responds to
WAIT mode. If the ASWAI control bit is clear, then the ATD ignores the
WAIT signal. The ATD response to the wait mode is to power down the
module. In this mode, the MCU does not have access to the control,
status or result registers.
When debugging an application, it is useful to have the ATD pause when
a breakpoint is encountered. To accommodate this, there are two
FREEZE bits in the ATDCTL3 register used to select one of three
responses:
Control and timing logic is static allowing the register contents and timing
position to be remembered indefinitely. The analog electronics remains
powered up; however, internal leakage may compromise the accuracy
of a frozen conversion depending on the length of the freeze period.
When the BDM signal is negated clock activity resumes.
Access to the ATD register file is possible during the ‘frozen’ period.
The ATD module is reset on two different events.
The single difference between the two events is that the RST bit event
does not reset the ADPU bit to its reset state value - i.e. the module is
not reset into a powered down state and will be returned to an idle state.
1. The ATD module may ignore the freeze request.
2. It may respond to the freeze request by finishing the current
3. It may respond by immediately ‘freezing’.
1. In the case of a system reset.
2. If the RST bit in the ATDTEST register is activated.
