Description
Address 0 select bit.
Internal registers address selection.
Address 1 select bit.
Internal registers address selection.
Address 2 select bit.
Internal registers address selection.
Address 3.
A3 is used to select Channel A or Channel B. A logic LOW selects
Channel A, and a logic HIGH selects Channel B. (See
Table 3
.)
Carrier Detect (active LOW).
These inputs are associated with individual UART
Channel A and Channel B. A logic LOW on these pins indicates that a carrier has been
detected by the modem for that channel. The state of these inputs is reflected in the
Modem Status Register (MSR).
Chip Select (active LOW).
This pin enables data transfers between the user CPU and
the SC68C752B for the channel(s) addressed. Individual UART sections (A, B) are
addressed by A3. See
Table 3
.
Clear to Send (active LOW).
These inputs are associated with individual UART
Channel A and Channel B. A logic 0 (LOW) on the CTS pins indicates the modem or
data set is ready to accept transmit data from the SC68C752B. Status can be tested by
reading MSR[4]. These pins only affect the transmit and receive operations when
Auto-CTS function is enabled via the Enhanced Feature Register EFR[7] for hardware
flow control operation.
