RL78/F13, F14 CHAPTER 2 PIN FUNCTIONS
R01UH0368EJ0210 Rev.2.10 71
Dec 10, 2015
(f) TI01, TI14, TI16
These are pins for inputting an external count clock/capture trigger to 16-bit timers. TI14 and TI16 are provided
only in the 100-pin products of RL78/F14.
(g) TO01, TO14, TO16
These are timer output pins of 16-bit timers. TO14 and TO16 are provided only in the 100-pin products of RL78/F14.
(h) SNZOUT0
This is a SNOOZE status output pin.
(i) TRDIOD1
This is a timer output pin of timer RD.
(j) STOPST
This is a STOP status output pin.
2.2.4 P40 to P47 (Port 4)
P40 to P47 function as an I/O port. These pins also function as data I/O for a flash memory programmer/debugger, timer
I/O, comparator output, external interrupt request input, SNOOZE status output, and LIN serial data I/O.
Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 4 (PU4).
For the P43 pin, the input threshold level can be specified using the port input threshold control register 4 (PITHL4).
The following operation modes can be specified in 1-bit units.
(1) Port mode
P40 to P47 function as an I/O port. These pins can be set to input or output port in 1-bit units using port mode register 4
(PM4).
(2) Control mode
P40 to P47 function as data I/O for a flash memory programmer/debugger, timer I/O, comparator output, external interrupt
request input, SNOOZE status output, and LIN serial data I/O.
(a) TOOL0
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).
(b) TI07, TI10, TI12
These are pins for inputting an external count clock/capture trigger to 16-bit timers.
(c) TO07, TO10, TO12
These are timer output pins of 16-bit timers.
(d) TRJIO0
This is a timer I/O pin of timer RJ.
(e) VCOUT0
This is a comparator output pin. This pin is provided only in the 100-pin products of RL78/F14.
