Note: The MRESET/SCK2 pin functions as the MRESET manual reset pin when a manual reset is
executed. The MD1/TxD2, MD2/RxD2, and MD8/5765 pins function as the MD1, MD2, and
MD8 mode input pins after a power-on reset. These pins are made to function as serial pins
by performing SCIF operation settings with the TE and RE bits in SCSCR2 and the MCE bit
in SCFCR2. Break state transmission and detection can be set in the SCIF's SCSPTR2
register.
