Product data sheet
6.1 Internal registers
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.
The SC16C750B provides 12 internal registers for monitoring and control. These registers
are shown in
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.
