ister can be used as outputs or inputs. In addition, R0
serves the functions of the various following special fea-
tures.
R10~R17
: R1 is an 8-bit high-voltage CMOS bidirectional
I/O port. R1 pins 1 or 0 written to the Port Direction Reg-
ister can be used as outputs or inputs.
R20~R27
: R2 is an 8-bit high-voltage CMOS bidirectional
I/O port. R2 pins 1 or 0 written to the Port Direction Reg-
ister can be used as outputs or inputs.
R30~R35
: R3 is a 6-bit high-voltage CMOS bidirectional
I/O port. R3 pins 1 or 0 written to the Port Direction Reg-
ister can be used as outputs or inputs.
R40~R43
: R4 is a 4-bit CMOS bidirectional I/O port. R4
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs. In addition, R4 serves the func-
tions of the following special features.
R50~R57
: R5 is an 8-bit CMOS bidirectional I/O port. R5
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs. In addition, R5 serves the func-
tions of the various following special features.
R60~R67
: R6 is an 8-bit CMOS bidirectional I/O port. R6
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs. In addition, R6 is shared with the
ADC input.
R70~R73
: R7 is a 4-bit CMOS bidirectional I/O port. R6
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs. In addition, R7 is shared with the
ADC input.
SX
IN
: Input to the internal subsystem clock operating cir-
cuit. In addition, SXIN serves the R74 pin when selected
by the code option. *R74 has a Pull-up circuit.
SX
OUT
: Output from the inverting subsystem oscillator
amplifier. In addition, SXOUT serves the R75 pin when
