Section 22 Power-Down Modes
22.12
Usage Notes
22.12.1 I/O Port Status
The status of the I/O ports is retained in software standby mode. Therefore, while a high level is
output or the pull-up MOS is on, the current consumption is not reduced by the amount of current
to support the high level output.
22.12.2 Current Consumption when Waiting for Oscillation Stabilization
The current consumption increases during oscillation stabilization.
22.12.3 DTC Module Stop Mode
If the DTC module stop mode specification and DTC bus request occur simultaneously, the bus is
released to the DTC and the MSTP bit cannot be set to 1.
After completing the DTC bus cycle, set the MSTP bit to 1 again.
