Chip Select A, B (active LOW). This function is associated
with individual channels, A through B. These pins enable data
transfers between the user CPU and the SC16C2550B for the
channel(s) addressed. Individual UART sections (A, B) are
addressed by providing a logic 0 on the respective CSA, CSB
pin.

I/O
Data bus (bidirectional). These pins are the 8-bit, 3-state data
bus for transferring information to or from the controlling CPU.
D0 is the least signicant bit and the rst data bit in a transmit
or receive serial data stream.

Interrupt A, B (3-state). This function is associated with
individual channel interrupts, INTA, INTB. INTA, INTB are
enabled when MCR bit 3 is set to a logic 1, interrupts are
enabled in the Interrupt Enable Register (IER) and is active
when an interrupt condition exists. Interrupt conditions include:
receiver errors, available receiver buffer data, transmit buffer
empty or when a modem status ag is detected.

I
Read strobe (active LOW strobe). A logic 0 transition on this
pin will load the contents of an internal register dened by
address bits A0 to A2 onto the SC16C2550B data bus
(D0 to D7) for access by external CPU.

I
Write strobe (active LOW strobe). A logic 0 transition on this
pin will transfer the contents of the data bus (D0 to D7) from the
external CPU to an internal register that is dened by address
bits A0 to A2.

O
Output 2 (user-dened). This function is associated with
individual channels, A through B. The state at these pin(s) are
dened by the user and through MCR register bit 3. INTA, INTB
are set to the active mode and OP2 to logic 0 when MCR[3] is
set to a logic 1. INTA, INTB are set to the 3-state mode and
OP2 to a logic 1 when MCR[3] is set to a logic 0. See Table 18
“Modem Control Register bits description”, bit 3 (MCR[3]).
Since these bits control both the INTA, INTB operation and
OP2 outputs, only one function should be used at one time, INT
or OP2.
