NOTE:
Timing specifications for nBATT_FAULT and/or nVDD_FAULT asserted deep-sleep mode entry are
below:
Fault assert
Delay between nBATT_FAULT or
nVDD_FAULT assertion (during all
modes of operation including sleep
mode) and deep-sleep mode entry

(The
de-assertion of SYS_EN defines when
the processor is in deep-sleep mode)
0.33
1.56
msec
NOTES:
1. -1ms if not using DC2DC
2. 0.15ms less time if exiting from Deep-sleep mode to 13M mode
3. Add 0.1ms if the wake up event is external
4. Oscillator start/crystal stable times are programmable (300uS-11mS)
NOTE:
6ms is user programmable using the OSCC[OSD] bit. The remaining 5ms is an internal timer which
counts until the oscillator is stable. (Typical stabilization is 500
μ
s. Maximum can be upto 5ms)
5. nRESET_OUT and nVDD_FAULT are programmable during sleep mode
6. Assumes PMCR[BIDAE or VIDAE] bits are set to zero (default state) - The PMCR[BIDAE or VIDAE] bits
are only read by the processor if nBATT_FAULT or nVDD_FAULT signals are asserted
