The WM8310 can also indicate the status of the SYSOK signal via a GPIO pin configured as a
“SYSVDD Good” output (see Section 21). A GPIO pin configured as “SYSVDD Good” output will be
asserted when the SYSVDD is above the SYSOK threshold.

SYSLO Error Action
Selects the action taken when SYSLO is
asserted
00 = Interrupt
01 = WAKE transition
10 = Reserved
11 = OFF transition
SYSLO Status
0 = Normal
1 = SYSVDD is below SYSLO threshold
SYSLO threshold (falling SYSVDD)
This is the falling SYSVDD voltage at
which SYSLO will be asserted
000 = 2.8V
001 = 2.9V
…
111 = 3.5V
SYSOK threshold (rising SYSVDD)
This is the rising SYSVDD voltage at
which SYSLO will be de-asserted
000 = 2.8V
001 = 2.9V
…
111 = 3.5V
