These registers are accessible only when LCR[7] is a logic 0.
These registers are accessible only when LCR[7] is a logic 1.
Enhanced Feature Register, Xon1, 2 and Xoff1, 2 are accessible only when the LCR is set to
‘BF(HEX)’.
6.2 FIFO operation
The 64-byte transmit and receive data FIFOs are enabled by the FIFO Control
Register bit-0 (FCR[0]). With 16C550 devices, the user can set the receive trigger
level, but not the transmit trigger level. The SC16C750 provides independent trigger
levels for both receiver and transmitter. To remain compatible with SC16C550, the
transmit interrupt trigger level is set to 16 following a reset. It should be noted that the
user can set the transmit trigger levels by writing to the FCR register, but activation
will not take place until EFR[4] is set to a logic 1. The receiver FIFO section includes
a time-out function to ensure data is delivered to the external CPU. An interrupt is
generated whenever the Receive Holding Register (RHR) has not been read
following the loading of a character or the receive trigger level has not been reached.
