Receive Ready (active LOW).
RXRDYA or RXRDYB goes LOW when the trigger level
has been reached or the FIFO has at least one character. It goes HIGH when the RX
FIFO is empty.
Transmit data A, B.
These outputs are associated with individual serial transmit
channel data from the SC68C752B. During the local loop-back mode, the TX output pin
is disabled and TX data is internally connected to the UART RX input.
Transmit Ready (active LOW).
TXRDYA or TXRDYB go LOW when there are at least a
trigger level number of spaces available or when the FIFO is empty. It goes HIGH when
the FIFO is full or not empty.
Power supply input.
Crystal or external clock input.
Functions as a crystal input or as an external clock
input. A crystal can be connected between XTAL1 and XTAL2 to form an internal
oscillator circuit (see
Figure 12
). Alternatively, an external clock can be connected to
this pin to provide custom data rates.
Output of the crystal oscillator or buffered clock.
(See also XTAL1.) XTAL2 is used
as a crystal oscillator output or a buffered clock output.
