Functions
I
This pin is for interfacing the request to send (RTS) signal. When RTSB sets to an “L” level,
transmission begins. When RTSB sets to an “H” level, transmission stops.
O
This pin is for interfacing the clear to send (CTS) signal. When CTSB sets to an “L” level,
transmission can proceed. When CTSB sets to an “H” level, transmission will not be accepted.
This pin is for interfacing received line signal detect (RLSD). When RLSDB sets to an “L” level
O and transmission is set to proceed, this pin functions as a timing signal for transmitting
transmission data to a terminal.
I
This pin is for input of transmit data (TXD).
O This pin is for output of receive data (RXD).
O This pin is for clock output using transmit-receive data.
I
This is the external input clock pin for use with Group 2.
