functions
P14/SI10/RxD1/ To use P14/SI10/RxD1/SDA10/INTP4 and P15/SCK10/SCL10/INTP7 as a general- p.133 _†
SDA10/INTP4, purpose port, note the serial array unit 0 setting. For details, refer to Table 14-7
P15/SCK10/SCL Relationship Between Register Settings and Pins (Channel 2 of unit 0: CSI10,
10/INTP7
UART1 Transmission, IIC10)
P16/TO05/TI05/ To use P16/TO05/TI05/INTP10 as a general-purpose port, set bit 5 (TO05) of timer p.133 _†
INTP10
output register 0 (TO0) and bit 5 (TOE05) of timer output enable register 0 (TOE0) to
“0”, which is the same as their default status setting.
Port 2
Make the AVDD0 pin the same potential as the EVDD or VDD pin when port 2 is used as p.138 _†
a digital port.
P30/TO00/TI03/ To use P30/TO00/TI03/RTC1HZ/INTP1 as a general-purpose port, set bit 5 p.142 _†
RTC1HZ/INTP1 (RCLOE1) of real-time counter control register 0 (RTCC0), bit 0 (TO00) of timer
output register 0 (TO0) and bit 0 (TOE00) of timer output enable register 0 (TOE0) to
“0”, which is the same as their default status setting.
P31/TO03/TI00/ To use P31/TO03/TI00/RTCDIV/RTCCL/PCLBUZ1/INTP2 as a general-purpose port, p.142 _†
RTCDIV/RTCCL/ set bit 4 (RCLOE0) of real-time counter control register 0 (RTCC0), bit 6 (RCLOE2) of
PCLBUZ1/INTP2 real-time counter control register 2 (RTCC2), bit 3 (TO03) of timer output register 0
(TO0), bit 3 (TOE03) of timer output enable register 0 (TOE0) and bit 7 of clock
output select register 1 (CKS1) to “0”, which is the same as their default status
setting.
P32/TO01/TI01/ To use P32/TO01/TI01/INTP5/PCLBUZ0 as a general-purpose port, set bit 1 (TO01) p.142 _†
INTP5/PCLBUZ0 of timer output register 0 (TO0), bit 1 (TOE01) of timer output enable register 0
(TOE0) and bit 7 of clock output select register 0 (CKS0) to “0”, which is the same as
their default status setting.
P33/TO07/TI07/ To use P33/TO07/TI07/INTP3 and P34/TO06/TI06/INTP8 as a general-purpose port, p.142 _†
INTP3,
set bit 7, 6 (TO07, TO06) of timer output register 0 (TO0), and bit 7, 6 (TOE07,
P34/TO06/TI06/I TOE06) of timer output enable register 0 (TOE0) to “0”, which is the same as their
NTP8
default status setting.
P40, P41
When a tool is connected, the P40 pin cannot be used as a port pin.
p.144 _†
When the on-chip debug function is used, P41 pin can be used as follows by the
mode setting on the debugger.
• 1-line mode: can be used as a port (P41).
• 2-line mode: used as a TOOL1 pin and cannot be used as a port (P41).
P60/SCL0,
When using P60/SCL0 and P61/SDA0 as a general-purpose port, stop the operation p.150 _†
P61/SDA0
of serial interface IICA.
P75/SCK01/KR5, To use P75/SCK01/KR5, P76/SI01/KR6 and P77/SO01/KR7, as a general-purpose p.151 _†
P76/SI01/KR6, port, note the serial array unit 0 setting. For details, refer to Table 14-6 Relationship
P77/SO01/KR7 Between Register Settings and Pins (Channel 1 of unit 0: CSI01, UART0 Reception).
P80/SCK00/
To use P80/SCK00/INTP11, P81/RxD0/SI00/INTP9 and P82/SO00/TxD0, as a p.156 _†
INTP11,
general-purpose port, note the serial array unit 0 setting. For details, refer to Table
P81/RxD0/SI00/ 14-5 Relationship Between Register Settings and Pins (Channel 0 of unit 0: CSI00,
INTP9,
UART0 Reception).
