SP5100 Power on Sequence and Timing
Note 10:
The following figure shows the timing of SB PWR_GOOD de-asserted to RSMRST#
de-asserted during a power down sequence. However, this timing only applies to S0 to G3
state transition, because G3 state is where both signals are inactivated.
SB PWR_GOOD
T14
RSMRST#
S0 to G3

Note 11:
On first power up, G3
S5, or after RSMRST# assertion, the LDT_STP# will be asserted
with CPU_VDDIO power. On subsequent power up, S5
S0, the timing on T9B will apply.
CPU_VDDIO
