Overview
The device internal structure includes a Z80 CPU interface, internal control
and interrupt logic, and two full-duplex channels. Associated with each
channel are read and write registers, and discrete control and status logic
that provides the interface to modems or other external devices.
The read and write register group includes five 8-bit control registers, two
sync-character registers, and two status registers. The interrupt vector is
written into an additional 8-bit register (Write Register 2) in Channel B that
may be read through Read Register 2 in Channel B. The registers for both
channels are designated as follows:
WR7–WR0 — Write Registers 0 through 7
RR2–RR0 — Read Registers 0 through 2
The bit assignment and functional grouping of each register is configured to
simplify and organize the programming process.
trate the functions assigned to each read or write register.
The logic for both channels provides formats, synchronization, and valida-
tion for data transferred to and from the channel interface. The modem
control inputs Clear to Send (CTS) and Data Carrier Detect (DCD) are
monitored by the discrete control logic under program control. All the
modem control signals are general purpose and can be used for functions
other than modem control.
For automatic interrupt vectoring, the interrupt control logic determines
which channel and which device within the channel has the highest priority.
Priority is fixed with Channel A assigned a higher priority than Channel B;
Receive, Transmit and External/Status interrupts are prioritized in that
order within each channel.
