Remark For how to connect a flash memory programmer using TOOLC1/P31, TOOLD1/P32, refer to CHAPTER 25
FLASH MEMORY. For how to connect TOOLC1/P31, TOOLD1/P32 and an on-chip debug emulator, refer
to CHAPTER 26 ON-CHIP DEBUG FUNCTION.
2.2.4 P60 and P61 (port 6)
P60 and P61 function as an I/O port. These pins also function as pins for serial interface data I/O, and clock I/O.
Input to the P60 and P61 pins can be specified through a normal input buffer or an SMBus input buffer in 1-bit units,
using port input mode register 6 (PIM6).
Output from the P60 and P61 pins can be specified as normal CMOS output or N-ch open-drain output (V
DD tolerance)
in 1-bit units, using port output mode register 6 (POM6).

P60/SCLA0/TxD6 P60/SCLA0/TxD6
P61/SDAA0/RxD6 P61/SDAA0/RxD6
The following operation modes can be specified in 1-bit units.
(1) Port mode
P60 and P61 function as an I/O port. P60 and P61 can be set to input port or output port in 1-bit units using port
mode register 6 (PM6). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 6 (PU6).
(2) Control mode
P60 and P61 function as serial interface data I/O and clock I/O.
(a) SDAA0
This is a serial data I/O pin for serial interface IICA.
(b) SCLA0
This is a serial clock I/O pin for serial interface IICA.
