Option
Bidirectional 8-bit input/output port. Each bit can be configured as a
wake-up input by ROM code option. The input or output mode is con-
trolled by PAC (PA control register).
Pull-high resistor options: PA0~PA7
Pull-low resistor options: PA0~PA5
CMOS/NMOS/PMOS options: PA0~PA7
Wake up options: PA0~PA7
PA6 and PA7 are pin-shared with TMR0 and TMR1 input, respectively.
PA0~PA5 can be used as USB mouse X1, X2, Y1, Y2, Z1, Z2 input for
mouse hardware wake-up function
PA6, PA7 can be used as USB mouse button input for mouse hardware
wake-up function
Bidirectional 8-bit input/output port. Software instructions determine the
CMOS output or Schmitt trigger input with pull-high resistor (determined
by pull-high options).
The PB can be used as analog input of the analog to digital converter
(determined by options).
PB6, PB7 can be used as USB mouse button input for mouse Hardware
wake-up function
Bidirectional I/O lines. Software instructions determine the CMOS out-
put or Schmitt trigger input with pull-high resistor (determined by 1-bit
pull-high option).
PD4 can be used as USB mouse button input for mouse hardware
wake-up function
