2.2.5 P40 to P43 (port 4)
programmer/debugger, clock output, and timer I/O.
(1) Port mode
(2) Control mode
36
P40 to P43 function as a 4-bit I/O port.
The following operation modes can be specified in 1-bit units.
(b) TI03
(c) TO03
(d) RTC1HZ
P40 to P43 function as an 4-bit I/O port. P40 to P43 can be set to input or output port in 1-bit units using port
mode register 4 (PM4). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 4
(PU4).
Be sure to connect an external pull-up resistor to P40 when on-chip debugging is enabled (by using an option
byte).
P40 to P42 function as data I/O for a flash memory programmer/debugger, clock output, and timer I/O.
(a) TOOL0
(b) TOOL1
(c) TI04
(d) TO04
This is a pin for inputting an external count clock/capture trigger to 16-bit timer 03.
This is a timer output pin from 16-bit timer 03.
This is a real-time counter correction clock (1 Hz) output pin.
This is a data I/O pin for a flash memory programmer/debugger.
Be sure to pull up this pin externally when on-chip debugging is enabled (pulling it down is prohibited).
This is a clock output pin for a debugger.
When the on-chip debug function is used, P41/TOOL1 pin can be used as follows by the mode setting on the
debugger.
This is a pin for inputting an external count clock/capture trigger to 16-bit timers 04.
This is a timer output pin from 16-bit timers 04.
Caution The function of the P40/TOOL0 pin varies as described in (a) to (c) below.
1-line mode: can be used as a port (P41).
2-line mode: used as a TOOL1 pin and cannot be used as a port (P41).
In the case of (b) or (c), make the specified connection.
(a) In normal operation mode and when on-chip debugging is disabled (OCDENSET = 0) by
an option byte (000C3H)
=> Use this pin as a port pin (P40).
