2.2.11 P140 to P145 (port 14)
P140 to P145 function as a 6-bit I/O port. These pins also function as external interrupt request input, clock output,
buzzer output, serial interface data I/O, clock I/O, busy input, and strobe output pins.
The following operation modes can be specified in 1-bit units.
(1) Port mode
P140 and P141 function as a 6-bit I/O port. P140 and P141 can be set to input or output port in 1-bit units using
port mode register 14 (PM14). Use of an on-chip pull-up resistor can be specified by pull-up resistor option
register 14 (PU14).
(2) Control mode
P140 to P145 function as external interrupt request input, clock output, buzzer output, serial interface data I/O,
clock I/O, busy input, and strobe output pins.
(a) INTP6, INTP7
These are the external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
(b) PCL
This is a clock output pin.
(c) BUZ
This is a buzzer output pin.
(d) BUSY0
This is a serial interface CSIA0 busy input pin.
(e) SIA0
This is a serial interface CSIA0 serial data input pin.
(f)
SOA0
This is a serial interface CSIA0 serial data output pin.
(g) SCKA0
This is a serial interface CSIA0 serial clock I/O pin.
(h) STB0
This is a serial interface CSIA0 strobe output pin.
2.2.12 AVREF
This is the A/D converter reference voltage input pin and the positive power supply pin of P20 to P27 and A/D
converter.
When the A/D converter is not used, connect this pin directly to EVDD or VDD
Note.
Note Make the AVREF pin the same potential as the VDD pin when port 2 is used as a digital port.
