Note: Unlisted bits of the registers are reserved.
22.5.2
DTC Module Stop: Depending on the operating status of the DTC, the MSTPA7 and MSTPA6
bits may not be set to 1. Setting of the DTC module stop mode should be carried out only when
the respective module is not activated.
For details, refer to section 8, Data Transfer Controller (DTC).
On-Chip Supporting Module Interrupt: 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 the 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.
Restrictions on Use in Medium-speed Mode: In medium-speed mode, registers of the HCAN,
LCD controller, and motor control PWM timer musts not be written to.
The write value must always be 1.
