Module Stop Mode
25.5.1
Module Stop Mode
Module stop mode can be set for individual on-chip supporting modules.
When the corresponding MSTP bit in MSTPCR is set to 1, module operation stops at the end of
the bus cycle and a transition is made to module stop mode. The CPU continues operating
independently.
Table 25.4 shows MSTP bits and the corresponding on-chip supporting modules.
When the corresponding MSTP bit is cleared to 0, module stop mode is cleared and the module
starts operating again at the end of the bus cycle. In module stop mode, the internal states of
modules other than the SCI, A/D converter, 8-bit PWM module, and 14-bit PWM module, are
retained.
After reset release, all modules other than the DTC are in module stop mode.
When an on-chip supporting module is in module stop mode, read/write access to its registers is
disabled.
