Pin function
Note:
The pin function is switched as shown below according to the combination of bit C/A in SMR
of SCI_2, bits CKE0 and CKE1 in SCR, bit ITS2 in ITSR, and bit P52DDR.
The pin function is switched as shown below according to the combination of bit RE in SCR of
SCI_2, bit ITS1 in ITSR, and bit P51DDR.
The pin function is switched as shown below according to the combination of bit TE in SCR of
SCI_2, bit ITS0 in ITSR, and bit P50DDR.
