Description
ADC reference voltage
ADC Analog Vdd
ADC Analog Vss
Sound DAC outputs
Keyboard scan outputs
Keyboard scan inputs
Power on reset input. Schmitt level input, with pullup.
Wake-up “on-key” input. Low causes PMU to exit standby state.
Reset input (also driven out in POR, until the PLL is locked)
Adapter power OK.
Main battery OK.
RTC oscillator input
RTC oscillator output
Main oscillator input
Main oscillator output
Low to enable PLL. High to bypass PLL with clock from OSCIN.
PLL analog power supply
PLL analog ground input
External PLL loop filter input/output pins (1 per PLL)
JTAG boundary scan and debug test clock
JTAG boundary scan and debug test reset
JTAG boundary scan and debug test mode select
JTAG boundary scan and debug test data input
JTAG boundary scan and debug test data output
Test mode select
Core Vdd supply
