Description
SCPT1 Mode
These bits select pin function and input pull-up MOS
control.
00: Other functions (see table 19.1)
01: Port output
10: Port input (pull-up MOS: On)
11: Port input (pull-up MOS: Off)
SCPT0 Mode
These bits select pin function and input pull-up MOS
control.
When TE = 0 and RE = 0 in SCSCR_0, 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_0, the SCPT0/TxD0 pin
functions as TxD0.
When RE = 1 in SCSCR_0, the SCPT0/RxD0 pin
functions as RxD0.
Note: Since two pins (TxD0 and RxD0) are used to
access one bit (SCPT0), there is no combination of
simultaneous input/output of SCPT0.
When port input is set (when bit SCP0MD1 is set to 1),
the TxD0 pin enters an output state when the TE bit in
SCSCR_0 is set to 1, whereas it enters high-impedance
state when the TE bit is cleared to 0.
