SC16C650B
UART with 32-byte FIFOs and IrDA encoder/decoder
6.1 Internal registers
The SC16C650B provides 17 internal registers for monitoring and control. These registers
are shown in Table 3. 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). Beyond the general 16C550 features and capabilities, the
SC16C650B offers an enhanced feature register set (EFR, Xon1/Xoff1, Xon2/Xoff2) that
provides on-board hardware/software ow control. 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.
[3]
Enhanced Feature Register, Xon1, Xon2 and Xoff1, Xoff2 are accessible only when the LCR is set to BFh.
6.2 FIFO operation
The 32-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 SC16C650B 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
Table 3.
