As the A/D converter operates on a clock from OSC, it stops in stop mode, watch mode, and subactive
mode. The current flowing in the A/D converter ladder resistor is also cut in these low-power modes to
reduce power consumption.
When an analog input pin is selected by the A/D mode register, the pull-up MOS for that pin is
disabled.
Use of bit 0 of A/D data register-lower (ADRL) is prohibited, but with the emulator it should be written
with 1. This bit need not be written in the mask ROM and ZTAT
TM
versions, although writing 1 will
have no effect.
