SC16C652B
Dual UART with 32-byte FIFOs and IrDA encoder/decoder
6.1 UART A-B functions
The UART provides the user with the capability to bi-directionally transfer information
between an external CPU, the SC16C652B package, and an external serial device. A
logic 0 on chip select pins CSA and/or CSB allows the user to congure, send data,
and/or receive data via UART channels A-B. Individual channel select functions are shown
in Table 3.
6.2 Internal registers
The SC16C652B provides two sets of internal registers (A and B) consisting of
17 registers each for monitoring and controlling the functions of each channel of the
UART. These registers are shown in Table 4. The UART 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).
[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’.
