Usage Notes

27.12.1 I/O Port Status

The status of the I/O ports is retained in software standby mode. Therefore, when a high level is
output, the current consumption is not reduced by the amount of current to support the high level
output.

27.12.2 Current Consumption when Waiting for Oscillation Stabilization

The current consumption increases during oscillation stabilization.

27.12.3 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.
