RL78/F13, F14 CHAPTER 2 PIN FUNCTIONS

R01UH0368EJ0210 Rev.2.10 80

Dec 10, 2015

2.2.14 P150 to P157 (Port 15)

P150 to P157 function as an I/O port. These pins also function as serial interface data I/O, clock I/O, timer I/O, slave

select input, and SNOOZE status output. These pins are provided only in the 100-pin products of RL78/F14.

Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 15 (PU15).

For the P150, P152, and P153 pins, the input threshold level can be specified using the port input threshold control

(1) Port mode

P150 to P157 function as an I/O port. These pins can be set to input or output port in 1-bit units using port mode register

15 (PM15).

(2) Control mode

P150 to P157 function as serial interface slave select input, data I/O, clock I/O, and SNOOZE status output.

(a) SSI11

This is a slave select input pin of the CSI11 (SPI11) serial interface.

(b) SI11

This is a serial data input pin of the CSI11 serial interface.

This is a serial data output pin of the CSI11 serial interface.

(d) SCK11

This is a serial clock I/O pin of the CSI11 serial interface.

(e) SNZOUT4 to SNZOUT7

These are SNOOZE status output pins.

2.2.15 V

DD, EVDD0, EVDD1, VSS, EVSS0, EVSS1

(1) V

DD, EVDD0, EVDD1

DD is a positive power supply pin for the P33, P34, P80 to P87, P90 to P97

Note

, P100 to P105, P121 to P124, P137 and

the pins other than ports.

DD0 and EVDD1 are positive power supply pins for ports other than P33, P34, P80 to P87, P90 to P97

Note

, P100 to

P105, P121 to P124, and P137. EVDD1 is provided only in the 100-pin products of RL78/F14.

Note In products with 48 or fewer pins, V

DD is the positive power supply pin for all port pins.

In products with 64 or more pins, VDD and EVDD0 are the positive power supply pins for P92 to P95 of products of

groups B to E and of group A, respectively.

In products with 64 or more pins, V

DD and EVDD0 are the positive power supply pins for P96 and P97 of products of

group E and of groups A to D, respectively.
