Bit Bit Name
Initial
value R/W
Description
15 to 8 — All 0 R Reserved
These bits are always read as 0. The write value should
always be 0.
7 RTSIO 0 R/W RTS Port Input/Output
Indicates the input or output of
RTS pin. When RTS pin
is used as port outputting the RTSDT bit, the MCE bit of
FIFO control register (SCFCR) should be set to 0.
0: Not output the RTSDT bit to
RTS pin
1: Output the RTSDT bit to
RTS pin
6 RTSDT 1 R/W RTS Port Data
Indicates the data of
RTS pin used as port. Input/output
is specified by RTSIO bit. When output, the value of
RTSDT bit is outputted to
RTS pin. Whenever input or
output,
RTS pin status is read from RTSDT bit.
However Port Function of PFC (Pin Function Controller)
must be set to
RTS input/output.
0: Input/output data is low level
1: Input/output data is high level
5 CTSIO 0 R/W CTS Port Input/Output
Indicates the input or output of
CTS pin. When CTS pin
is used as port outputting the CTSDT bit, the MCE bit of
FIFO control register (SCFCR) should be set to 0.
0: Not output the CTSDT bit to
CTS pin
1: Output the CTSDT bit to
CTS pin
4 CTSDT 1 R/W CTS Port Data
Indicates the data of
CTS pin used as port. Input/output
is specified by CTSIO bit. When output, the value of
CTSDT bit is outputted to
CTS pin. Whenever input or
output,
CTS pin status is read from CTSDT bit.
However Port Function of PFC (Pin Function Controller)
must be set to
CTS input/output.
0: Input/output data is low level
1: Input/output data is high level
