5.7.7
The HCS08 provides one 8-channel analog-to-digital (ATD) module. The eight ATD channels share
Port B. Each channel individually can be configured for general-purpose I/O or for ATD functionality.
5.7.7.1
5.7.7.2
The ATD has two modes for low power
5.7.7.2.1
When the MCU goes into Stop Mode, the MCU stops the clocks and the ATD analog circuitry is turned
off, placing the module into a low-power state. Once in stop mode, the ATD module aborts any single or
continuous conversion in progress. Upon exiting stop mode, no conversions occur and the registers have
their previous values. As long as the ATDPU bit is set prior to entering stop mode, the module is
reactivated coming out of stop.
5.7.7.2.2
Clearing the ATDPU bit in register ATD1C also places the ATD module in a low-power state. The ATD
conversion clock is disabled and the analog circuitry is turned off, placing the module in power-down
mode. (This mode does not remove power to the ATD module.) Once in power-down mode, the ATD
module aborts any conversion in progress. Upon setting the ATDPU bit, the module is reactivated. During
power-down mode, the ATD registers are still accessible.

The reset state of the ATDPU bit is zero. Therefore, the module is reset into
the power-down state.
