RL78/D1A CHAPTER 2 PIN FUNCTIONS
(2) Control mode
P50 to P57 function as timer I/O, serial interface data I/O, and segment signal outputs for the LCD controller / driver.
(a) TI02 (P50), TI04 (P51), TI06 (P52) and TI13 (P53) to TI17 (P57)
These are the pins for inputting an external count clock/capture trigger to 16-bit timers 02, 04, 06, and 13 to 17.
(b) TO02 (P50), TO04 (P51), TO06 (P52) and TO13 (P53) to TO17 (P57)
These are the timer output pins of 16-bit timers 02, 04, 06 and 13 to 17.
(c) SO01 (P54), SO10 (P53)
These are the serial data output pins of serial interface CSI01 and CSI10.
(d) SI01 (P55), SI10 (P52)
These are the serial data input pins of serial interface CSI01 and CSI10.
(e) SCK01 (P56), SCK10 (P51)
These are the serial clock I/O pins of serial interface CSI01 and CSI10.
(f) SDA11 (P50)
This is a serial data I/O pin of serial interface for simplified I2C.
(g) SEG2 (P54) to SEG5 (P57), SEG49 (P50) to SEG52 (P53)
These are the segment signal output pins for the LCD controller/driver.
2.2.7 P60 to P66 (port6)
48-pin products: P60 and P61 function as a 2-bit I/O port.
64-pin products: P60 and P61 function as a 2-bit I/O port.
80-pin products: P60, P61, P65, and P66 function as a 4-bit I/O port.
100-pin products: P60 to P66 function as a 7-bit I/O port.
These pins also function as serial interface data I/O, timer I/O, real-time clock correction clock output, clock / buzzer
output, and external interrupt request input.
Input to the P61 and P63 pins can be specified through a normal Schmitt3 input buffer or a Schmitt1 input buffer in 1-bit
units, using port input mode register 6 (PIM6).
Output from the P60 and P61 pins can be specified as normal CMOS output or N-ch open-drain output (VDD tolerance)
in 1-bit units, using port output mode register 6 (POM6).
The following operation modes can be specified in 1-bit units.
(1) Port mode
48-pin products: P60 and P61 function as a 2-bit I/O port.
64-pin products: P60 and P61 function as a 2-bit I/O port.
80-pin products: P60, P61, P65, and P66 function as a 4-bit I/O port.
100-pin products: P60 to P66 function as a 7-bit I/O port.
P60 to P66 can be set to input or output port in 1-bit units using port mode register 6 (PM6). Use of an on-chip pull-up
resistor can be specified by pull-up resistor option register 6 (PU6).
(2) Control mode
P60 to P66 function as serial interface data I/O, timer I/O, real-time clock correction clock output, clock/ buzzer output,
and external interrupt request input.
