Options

Description

PA0~PA7

I/O

Wake-up,

Pull-high

or None

Bidirectional 8-bit I/O port, Each bit can be configured as a wake-up input by

configuration option. Software instructions determine if the pin is a CMOS out-

put or Schmitt trigger input. Configuration options determine which pins on

this port have pull-high resistors.

PB0/SDOB/SDAB

PB1/SCKB/SCLB

PB2/SDIB

PB3/SCSB

PB4/SDOA/SDAA

PB5/SCKA/SCLA

PB6/SDIA

PB7/SCSA

I/O

Pull-high

or None

Bidirectional 8-bit I/O port. Software instructions determine if the pin is a

CMOS output or Schmitt trigger input. Configuration options determine which

pins on this port have pull-high resistors. Pins PB0~PB3 are pin-shared with

SIMB control pins SDOB/SDAB, SCKB/SCLB, SDIB and SCSB respectively.

Pins PB4~PB7 are pin-shared with SIMA control pins SDOA/SDAA,

SCKA/SCLA, SDIA and SCSA respectively.

VSS

¾¾

Negative digital power supply, ground

VDD

¾¾

Positive digital power supply

VDD_PBIO

¾¾

PB I/O external positive power supply(determine by option)

PC0/RES

Schmitt trigger reset input or PC0 I/O pin. Configuration option determines if

the pin is as a reset pin or GPIO pin. Software instructions determine if this pin

has pull-high resistor.

PC1/OSC1

PC2/OSC2

Crystal,

ERC or

IRC

OSC1, OSC2 are connected to an external RC network, external crystal or no

connection, determined by configuration option, for the internal system clock.

If the ERC system clock option is selected, pin OSC2 can be as PC2. If the

IRC system clock option is selected, the OSC1/OSC2 pins will be IO pins

PC1/PC2. Software instructions determine which pins on this port have

pull-high resistors.

VSSA

¾¾

Negative DAC circuit power supply, ground

AUD

CMOS

Audio output for driving external transistor or power amplifier.

VDDA

¾¾

Positive DAC circuit power supply

VDDP

¾¾

PWM positive power supply

PWM1, PWM2

PWM circuit direct speaker drive

VSSP

¾¾

PWM negative power supply, ground

Note: Each pin on PA can be programmed through a configuration option to have a wake-up function.

Individual pins can be selected to have pull-high resistors.
