Intelligent Two-Channel LAN and WAN Communications Controller — CD2231
Datasheet
121
Bit 3
TxEn – Transmitter enabled status
When set, the transmitter is enabled.
When clear, the transmitter is disabled.
Bit 2
Reserved – must be ‘0’.
Bit 1
TFram – Transmit frame status
When set, a frame is being transmitted.
When clear, no frame is being transmitted.
Bit 0
TIdle – Transmitter idle status
When set, the transmitter output is idle.
When clear, the transmitter output is not idle.
Note that TFram and TIdle are mutually exclusive.
8.4.4
Modem Signal Value Registers (MSVR)
8.4.4.1
Modem Signal Value Register (MSVR-RTS)
8.4.4.2
Modem Signal Value Register (MSVR-DTR)
Either of these registers is read to determine the current input levels on the input modem pins. Note
that the pin definitions for these signals is negative true while the register values are positive true.
Two registers are provided for control of the outputs — DTR and RTS. Writing to the MSVR-DTR
register affects only the DTR pin. Writing to the MSVR-RTS register affects only the RTS pin.
Bit 7
DSR – Current state of data set ready input
Bit 6
CD – Current state of carrier detect input
Bit 5
CTS – Current state of clear to send input
Bit 4
DTR option – written by MSVR-DTR register
0 = value of DTR bit is output on TXCOUT/DTR* pin
1 = Transmit clock is output on TXCOUT/DTR* pin
