Appendix E Timing of Transition to and Recovery from Hardware Standby Mode
Timing of Transition to Hardware Standby Mode
(1) To retain RAM contents with the RAME bit set to 1 in SYSCR, drive the RES signal low at
(2) To retain RAM contents with the RAME bit cleared to 0 in SYSCR, or when RAM contents do
Timing of Recovery from Hardware Standby Mode
Drive the RES signal low and the NMI signal high approximately 100 ns or more before STBY
goes high to execute a power-on reset.
