Bi-directional 8-bit input/output port. Each bit can be configured as
wake-up input by option (bit option). Software instructions determine
if the pin is output or Schmitt Trigger input. When if output, Configura-
tion option may choose CMOS or NMOS. Configuration options de-
termine if the pins have pull-high resistors.
The TMR and INT are pin-shared with PA6 and PA7, respectively.
PA0~PA3 are shared with SPI function.
PA4~PA5 shared with PWM0~PWM1.
Bi-directional 8-bit input/output port. Software instructions determine
if the pin is a CMOS output or Schmitt Trigger input. Configuration op-
tions determine if the pins have pull-high resistors. PB is pin shared
with the A/D inputs. Once a PB line is selected as an A/D input, using
software control, the I/O function and pull-high resistor are disabled
automatically.
A configuration option determines whether PB7 is an I/O pin or a
power supply pin for PB0~PB6.
A configuration option determines whether the power supply for
PB0~PB6 is sourced from VDD or VDDIO
PB0 shared with PWM2.
Bi-directional 8-bit input/output port. Software instructions determine
if the pin is a CMOS output or Schmitt Trigger input. Configuration op-
tions determine if the pins have pull-high resistors. PC is pin shared
with the A/D inputs. Once a PB line is selected as an A/D input, using
software control, the I/O function and pull-high resistor are disabled
automatically
OSCI, OSCO are connected to an external 6MHz or 12MHz Crys-
tal/resonator, determined by software instructions, for the internal
system clock
