2.2.9 P90 to P97 (Port 9)
P90 to P97 function as an I/O port. These pins also function as A/D converter analog input.
The following operation modes can be specified in 1-bit units.
(1) Port mode
P90 to P97 function as an I/O port. These pins can be set to input or output port in 1-bit units using port mode register 9
(PM9).
(2) Control mode
P90 to P97 function as A/D converter analog input.
(a) ANI10 to ANI17 (100-pin products of RL78/F14)
These are analog input pins of the A/D converter. For details, see 12.10 (5) Analog input (ANIn) pins.
(b) ANI10 to ANI15, ANI26, ANI27 (80-pin products of RL78/F13 (CAN and LIN incorporated))
These are analog input pins of the A/D converter. For details, see 12.10 (5) Analog input (ANIn) pins.
2.2.10 P100 to P107 (Port 10)
P100 to P107 function as an I/O port. These pins are provided only in the 100-pin products of RL78/F14. These pins
also function as A/D converter analog input and LIN serial data I/O.
For P106 and P107, use of an on-chip pull-up resistor can be specified by pull-up resistor option register 10 (PU10).
For the P107 pin, the input threshold level can be specified using the port input threshold control register 10 (PITHL10).
The following operation modes can be specified in 1-bit units.
(1) Port mode
P100 to P107 function as an I/O port. These pins can be set to input or output port in 1-bit units using port mode register
10 (PM10).
(2) Control mode
P100 to P107 function as A/D converter analog input and LIN serial data I/O.
(a) ANI18 to ANI23
These are analog input pins of the A/D converter. For details, see 12.10 (5) Analog input (ANIn) pins.
(b) LTXD1
This is a serial data output pin for the LIN. LTXD1 is provided only in 100-pin products of RL78/F14.
(c) LRXD1
This is a serial data output pin for the LIN. LRXD1 is provided only in 100-pin products of RL78/F14.
