Timing of Transition to Hardware Standby Mode
(1) To retain RAM contents when the RAME bit in SYSCR is set to 1, drive the RES signal low
(2) When the RAME bit in SYSCR is cleared to 0 or when it is not necessary to retain RAM
Timing of Recovery From Hardware Standby Mode: Drive the RES signal low approximately
100 ns before STBY goes high.
