6.4 Internal registers
The SC16C654/654D provides 15 internal registers for monitoring and control. These
registers are shown in
Table 5
. Twelve registers are similar to those already available
in the standard 16C554. These registers function as data holding registers
(THR/RHR), interrupt status and control registers (IER/ISR), a FIFO control register
(FCR), line status and control registers (LCR/LSR), modem status and control
registers (MCR/MSR), programmable data rate (clock) control registers (DLL/DLM),
and a user accessible scratchpad register (SPR). Beyond the general 16C554
features and capabilities, the SC16C654/654D offers an enhanced feature register
set (EFR, Xon/Xoff1-2) that provides on-board hardware/software flow control.
Register functions are more fully described in the following paragraphs.

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).
6.5 FIFO operation
The 64-byte transmit and receive data FIFOs are enabled by the FIFO Control
Register (FCR) bit 0. With SC16C554 devices, the user can set the receive trigger
level, but not the transmit trigger level. The SC16C654/654D provides independent
trigger levels for both receiver and transmitter. To remain compatible with SC16C554,
the transmit interrupt trigger level is set to 8 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
