~ INT6)
4
(15 ~ 18)
Input/output
Port 60 ~ 63: A 4-bit input/output port. Functions as an input port after reset.
Input
Interrupt request pins 3-6: Input pins for generating interrupt requests at rise edges.
P64
(TI0)
1
(19)
Input/output
Port 64: A 1-bit input/output port. Functions as an input port after reset.
Input
Timer input 0: The timer 0 clock input pin.
P65
(TI2)
1
(20)
Input/output
Port 65: A 1-bit input/output port. Functions as an input port after reset
Input
Timer input 2: The timer 2 clock input pin.
P66
(TO0/TO1)
1
(22)
Input/output
Port 66: A 1-bit input/output port. Functions as an input port after reset.
Output
Timer output 0/1: The timer 0 or timer 1 output pin.
P67
(TO2/TO3)
1
(23)
Input/output
Port 67: A 1-bit input/output port. Functions as an input port after reset.
Output
Timer output 2/3: The timer 2 or timer 3 output pin.
LATWAIT
RxD0
1
(30)
Input
Set serial channel 0 to the TPH mode after reset. The wait control input pin used to cause
TPHLAT output to wait.
Used as the receive data input pin when serial channel 0 is set to the Normal mode.
TPHSD
(TxD0)
1
(31)
Output
Serial channel 0 enters the TPH mode and outputs “0” after a reset. The TPHSD pin is used
to output transmit data to TPH.
When set to the Normal mode, serial channel 0 functions as the transmit data output pin
TXD0 output immediately after mode is set.
TPHCKO
(SCLK0)
1
(32)
Output
After a reset, serial channel 0 enters the TPH mode and outputs “1”. The TPHCK0 pin is used
to output the transmit clock to TPH.
Input/output
When set to the Normal mode by the TPH control register, serial channel 0 operates in the
UART or I/O interface mode.
The control register of serial channel 0 determines whether the UART or I/O interface mode is
used.
In the I/O interface mode, either the external clock from SCLK0 or the transmit/receive clock
from the internal baud rate generator is output. Note: When operating with external clock
inout in the I/O interface mode SCLK0 is output after a reset; therefore, use an open drain
circuit to connect the external clock to the SCLK0 pin.
