Receive FIFO Almost Full (status).
0 = Receive FIFO (12 deep) contains 3 or more empty locations (RXF = 9). The host can clear the
RXF interrupt without emptying the RX FIFO by writing a 0 to the RXF bit. This will disable the RXF
interrupt until the host has emptied the FIFO.
1 = Receive FIFO contains 2 or less empty locations (RXF = 10).
Transmit FIFO Almost Empty (status).
0 = Transmit FIFO (14 deep) contains 3 or more characters (TXF = 3).
1 = Transmit FIFO contains 2 or less characters (TXF = 2).
Note: TXE interrupt will not trigger if the CTS bit is inactive. Therefore, the host does not need to
poll CTS while waiting for transmit FIFO to empty. TXE can be cleared by writing it to 0.
Receive FIFO Empty.
0 = Receive FIO has valid data.
1 = Receive FIFO empty.
Note: If the interim timer (see PTMR – U6F, bits 7:0) set by PTMR expires, it will cause an
interrupt. This interrupt will not set RXF, TXE or INT. The interrupt handler on the host should then
verify that REM = 0 and begin to empty the receive FIFO (Parallel Interface 0 register) until REM =
1.
Interrupt Mask.
0 = In parallel mode, the –INT pin is triggerd by a rising edge on RXF or TXE only (default).
1 = In parallel mode, the –INT pin is trigged by a rising edge on RXF, TXE or INT.
Interrupt
0 = No interupt has occurred.
1 = Indicates that an interrupt (CID, OCD, PPD, RI, or DCD from U70) has occurred. This bit is
cleared via the AT:I command.
Escape.
Operation of this bit in parallel mode is functionally equivalent to the ESC pin in serial mode.
Request-to-send
Operation of this bit in parallel mode is functionally eqivalent to the –RTS pin in serial mode. Use of
the –CTS and –RTS bits (as opposed to the TXE and RXF bits) allows the flow control between the
host and the modem to operate one byte at a time, rather than in blocks.
Clear-to-Send
Operation of this bit in parallel mode is functionally equivalent to the –CTS pin in serial mode. Use
of the –CTS and –RTS bits (as opposed to the TXE and RXF bits) allows the flow control between
the host and the modem to operate one byte at a time, rather than in blocks.
