set low during sleep and SPI pins are set high. Peripheral and SPI pins resume normal operation upon
wake.
Digital I/O lines that have been set using I/O line passing hold their values during sleep, however the
digital timeout timer (
T0
through
T9
, and
Q0
through
Q2
) are suspended during sleep and resume
upon wake.
Analog and PWM I/O Lines
Lines configured as analog inputs or PWM output are not affected during sleep. PWM lines are shut
down (set low) during sleep and resume normal operation upon wake.
PWM output pins set by analog line passing are shutdown during sleep and revert to their preset
values (
M0
and
M1
) on wake. This happens regardless of whether the timeout has expired or not.
