I
Clock Input. - This function is associated with 28 pin
ST16C1551CJ28 package only. An external clock must be
connected to this pin to clock the baud rate generator and
internal circuitry (see Programmable Baud Rate Genera-
tor).

I
Chip Select (active low) - A logic 0 on this pin selects the
UART I/O for external access. Data can be transferred
between the user CPU and the 155X or the 155X and the
CPU.

I/O
Data Bus (Bi-directional) - These pins are the eight bit, tri-
state data bus for transferring information to or from the
controlling CPU. D0 is the least significant bit and the first
data bit in a transmit or receive serial data stream.

O
Interrupt (three state, active high) - This function is associ-
ated with UART channel interrupts (INT). INT is enabled
when MCR bit-3 is set to a logic 1, interrupts are enabled in
the interrupt enable register (IER), and when an interrupt
condition exists. Interrupt conditions include: receiver er-
rors, available receiver buffer data, transmit buffer empty,
or when a modem status flag is detected.

I
Read strobe. (active low strobe) - A logic 0 transition on this
pin will load the contents of an Internal register defined by
address bits A0-A2 onto the 155X data bus (D0-D7) for
access by an external CPU.
