Description
PA0~PA2
PA3/PFD
PA4/TMR
PA5/INT
PA6/SDA
PA7/SCL
I/O
Pull-high
Wake-up
PA3 or PFD
I/O or Serial Bus
Bidirectional 8-bit input/output port. Each bit can be configured as wake-up
input by options. Software instructions determine the CMOS output or
Schmitt trigger input with or without pull-high resistor (determined by
pull-high options: bit option). The PFD, TMR and INT are pin-shared with
PA3, PA4 and PA5, respectively. Once the I
2
C Bus function is used, the in-
ternal registers related to PA6 and PA7 can not be used.
PB0/AN0
PB1/AN1
PB2/AN2
PB3/AN3
PB4/AN4
PB5/AN5
PB6/AN6
PB7/AN7
I/O
Pull-high
Bidirectional 8-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without pull-high resistor (deter-
mined by pull-high: port option) or A/D input.
Once a PB line is selected as an A/D input (by using software control), the
I/O function and pull-high resistor are disabled automatically.
PC0~PC4
I/O
Pull-high
Bidirectional 5-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without pull-high resistor (deter-
mine by pull-high option: port option).
