The system goes from active mode to sleep (high-speed) mode when a SLEEP instruction is
executed while the SSBY and LSON bits in SYSCR1 are cleared to 0, the MSON and DTON
bits in SYSCR2 are cleared to 0. In sleep mode CPU operation is halted but the on-chip
peripheral functions. CPU register contents are retained.
The system goes from active mode to sleep (medium-speed) mode when a SLEEP instruction
is executed while the SSBY and LSON bits in SYSCR1 are cleared to 0, the MSON bit in
SYSCR2 is set to 1, and the DTON bit in SYSCR2 is cleared to 0. In sleep (medium-speed)
mode, as in sleep (high-speed) mode, CPU operation is halted but the on-chip peripheral
functions are operational. The clock frequency in sleep (medium-speed) mode is determined
by the MA1 and MA0 bits in SYSCR1. CPU register contents are retained.
Furthermore, it sometimes acts with half state early timing at the time of transition to sleep
(medium-speed) mode.
