Timing of Transition to Hardware Standby Mode
(1) To retain RAM contents, drive the RES signal low 10 system clock cycles before the STBY
(2) When it is not necessary to retain RAM contents, RES does not have to be driven low as in
Timing of Recovery From Hardware Standby Mode: Drive the RES signal low approximately
100 ns before STBY goes high.
