F.1
(1) To retain RAM contents with the RAME bit set to 1 in SYSCR, drive the RES signal low at least 10 system clock
(2) To retain RAM contents with the RAME bit cleared to 0 in SYSCR, or when RAM contents do not need to be retained,
F.2
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.
cycles before the STBY signal goes low, as shown below. RES must remain low until STBY signal goes low (delay
from STBY low to RES high: 0 ns or more).
RES does not have to be driven low as in (1).
