Function
P110 to P117 I/O port P11
P120 to P127 I/O port P12
P130 to P137 I/O port P13
P140 to P147 I/O port P14
Input/output This is an 8-bit I/O port equivalent to P0. By software select-
ing, P110, P111 also function as clock output pins, which the
frequency is the same with XIN.
Input/output This is an 8-bit I/O port equivalent to P0. (Except that output
type is CMOS 3 state only.) By software selecting, this port
can be used for external interrupt input pin.
Input/output This is an 8-bit I/O port equivalent to P0. (Except that output
type is N channel open drain only; no internal pull-up regis-
ter support.)
Input/output This is an 8-bit I/O port equivalent to P0. The port can be
used for key on wake-up interrupt 1 input pins. P140 to P143
are available for directly driving LED's. In input mode, the
pull-up register can be set in one bit unit by software.
P150 to P157 I/O port P15
Input/output This is an 8-bit I/O port equivalent to P0. (Except that output
type is CMOS 3 state only.) By software selecting, these
ports can be used for timer A0 to A2's output or SI/O3 and
SI/O4 I/O pins.
P160, P161
I/O port P16
Input/output This is an 2-bit I/O port equivalent to P0. (Except that output
type is CMOS 3 state only.) By software selecting, this port
can be used for timer B3 and B4 input or PWM output pin.
