I/O type
Function
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.
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.
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.
