SC16C750B
5 V, 3.3 V and 2.5 V UART with 64-byte FIFOs
The rich feature set of the SC16C750B is available through internal registers. Automatic
hardware flow control, selectable transmit and receive FIFO trigger level, selectable TX
and RX baud rates, modem interface controls, and a sleep mode are some of these
features.
6.1 Internal registers
The SC16C750B provides 12 internal registers for monitoring and control. These registers
are shown in
Table 3
. These twelve registers are similar to those already available in the
standard 16C550. 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). Register functions are more fully described in the following
paragraphs.
[1]
These registers are accessible only when LCR[7] is a logic 0.
[2]
These registers are accessible only when LCR[7] is a logic 1.
