In standby mode, all clock supply stops and only the contents of the
internal DRAM are retained. The power requirement is only that which
the internal DRAM needs for refreshing itself. When set to standby
mode, the M32000D4BFP-80 waits for the current bus operation to
be completed. It then purges the cache memory and switches the
internal DRAM to self-refresh mode. After that, the PLL and all clock
supplies stop and the STBY signal goes to an "L" level to indicate the
completion of the switch to standby mode. Input an "L" level to WKUP
or RST to return from standby mode to normal operation mode. The
contents of the internal DRAM are retained upon return using the
WKUP signal.
In CPU sleep mode, clock supply to the M32R CPU stops. In this
mode, the internal DRAM, cache memory, memory controller and
external bus interface continue to operate and the internal DRAM
can be accessed from the external bus. Input an "L" level to INT, SBI
or RST to return to normal operation mode from CPU sleep mode.
The contents of the cache memory, internal DRAM, general-purpose
registers and programmable I/O control register are retained upon
return using the INT or SBI signals.
