BAUDOUT
UART with 32-byte FIFOs and IrDA encoder/decoder
Description
Register select. A0-A2 are used during read and write
operations to select the UART register to read from or write
to. Refer to
description.
Address strobe. When AS is active (LOW), A0, A1, and A2
and CS0, CS1, and CS2 drive the internal select logic
directly; when AS is HIGH, the register select and chip select
signals are held at the logic levels they were in when the
LOW-to-HIGH transition of AS occurred.
Baud out. BAUDOUT is a 16 clock signal for the
transmitter section of the UART. The clock rate is established
by the reference oscillator frequency divided by a divisor
specified in the baud generator divisor latches. BAUDOUT
may also be used for the receiver section by tying this output
to RCLK.
