Description
SCPT4 Mode
00: Other functions (see table 19.1)
01: Port output
10: Port input (pull-up MOS: On)
11: Port input (pull-up MOS: Off)
SCPT3 Mode
00: Other functions (see table 19.1)
01: Port output
10: Port input (pull-up MOS: On)
11: Port input (pull-up MOS: Off)
SCPT2 Mode
These bits select pin function and input pull-up MOS
control.
When TE = 0 and RE = 0 in SCSCR_2, operation is as
follows:
00: Other functions (see table 19.1)
01: Port output
10: Port input (pull-up MOS: On)
11: Port input (pull-up MOS: Off)
When TE = 1 in SCSCR_2, the SCPT2/TxD2 pin functions
as TxD2.
When RE = 1 in SCSCR_2, the SCPT2/RxD2 pin
functions as RxD2.
Note: Since two pins (TxD2 and RxD2) are used to access
one bit (SCPT2), there is no combination of
simultaneous input/output of SCPT2.
When port input is set (when bit SCP2MD1 is set to 1), the
TxD2 pin enters an output state when the TE bit in
SCSCR_2 is set to 1, whereas it enters high-impedance
state when the TE bit is cleared to 0.
