Notes 1: Clock supply to the M32R CPU stops and the M32000D3FP switches to CPU sleep mode in 1 internal
clock after "H'02" is written to the MPMR register.
2: When returning to normal operation mode, clock supply to the M32000D3FP CPU restarts and then
normal operation mode starts after 2 internal clocks from when the INT or SBI signal is input.
3: When starting the M32000D3FP in CPU sleep mode, the interrupt request is always accepted when an
"L" level signal of 1 CLKIN width is input to the INT pin or SBI pin, because they are continuously monitored.
In CPU sleep mode, since the memory controller and the external bus interface continue operating,
there is no change to bus control signals. From the system bus side, the state is the same as that
which exists in normal operation mode.
