Monosync mode, the transmitter transmits from WR6; the receiver
compares against WR7.
In the Monosync, Bisync, and External Sync modes, assembly of received
data continues until the Z80 SIO is reset, or until the receiver is disabled (by
command or by DCD in the Auto Enables mode), or until the CPU sets the
Enter Hunt Phase bit.
After initial synchronization has been achieved, the operation of the Mono-
sync, Bisync, and External Sync modes is similar. Any differences are spec-
ified in the following text.
Table 5 describes how WR3, WR4, and WR5 are used in synchronous
receive and transmit operations. WR0 points to other registers and issues
various commands, WR1 defines the interrupt modes, WR2 stores the
interrupt vector, and WR6 and WR7 store sync characters.
trates the typical program steps that implement a half-duplex Bisync
transmit operation.
