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 10
(2) To retain RAM contents with the RAME bit cleared to 0 in SYSCR, or when RAM contents
Timing of Recovery from Hardware Standby Mode
Drive the RES signal low approximately 100 ns before STBY goes high.
