Note: Bits 15, 11, 10, 8, and 4 to 0 can be read or written to, but do not affect operation.
18.5.2
DTC Module Stop Mode: Depending on the operating status of the DTC, the MSTP14 bit may
not be set to 1. Setting of the DTC module stop mode should be carried out only when the DTC is
not activated.
For details, refer to section 7, Data Transfer Controller.
On-Chip Supporting Module Interrupts: Relevant interrupt operations cannot be performed in
module stop mode. Consequently, if module stop mode is entered when an interrupt has been
requested, it will not be possible to clear the CPU interrupt source or DTC activation source.
Interrupts should therefore be disabled before entering module stop mode.
Writing to MSTPCR: MSTPCR should only be written to by the CPU.
