Description
Programmable Bank B GPIO pins.
Externally drives the 4390 JTAG enable pins
high/low under software control for debug
security purposes.
WLAN JTAG enable. This pin must be
connected to ground if the JTAG interface is
not used.
LNLDO input.
LDO VBAT.
External sleep clock input (32.768 KHz).
No connect.
OTP 3.3V supply.
Quiet ground. Connect to VSSC for ESD.
1.8V–3.3V supply for PMU controls. Must be
directly connected to VDDIO on the PCB.
Connect to Ground to reduce system RF
noise.
Connect to Ground to reduce system RF
noise.
