PIO1_25 — General purpose digital input/output pin.

CT32B0_MAT1 — Match output 1 for 32-bit timer 0.

PIO1_26 — General purpose digital input/output pin.

CT32B0_MAT2 — Match output 2 for 32-bit timer 0.

RXD — Receiver input for USART.

PIO1_27 — General purpose digital input/output pin.

CT32B0_MAT3 — Match output 3 for 32-bit timer 0.

TXD — Transmitter output for USART.

PIO1_28 — General purpose digital input/output pin.

CT32B0_CAP0 — Capture input 0 for 32-bit timer 0.

SCLK — Serial clock input/output for USART in

synchronous mode.

PIO1_29 — General purpose digital input/output pin.

SCK0 — Serial clock for SSP0.

CT32B0_CAP1 — Capture input 1 for 32-bit timer 0.

Not connected.

Not connected.

Input to the oscillator circuit and internal clock generator

circuits. Input voltage must not exceed 1.8 V.

Output from the oscillator amplifier.

Analog 3.3 V pad supply voltage: This should be

nominally the same voltage as VDD but should be isolated

to minimize noise and error. This voltage is used to power

the ADC. This pin should be tied to 3.3 V if the ADC is not

used.

ADC negative reference voltage: This should be

nominally the same voltage as VSS but should be isolated

to minimize noise and error. Level on this pin is used as a

reference for ADC.
