the form Lx|Hx,...Lx|Hx where x specifies which bit number
to write high (Hx) or low (Lx), and x may take the values
from 0-7. For example, WR 1.1-2,X,L1,L3;H0,H1 would
cause bits 1 and 3 to go low in port 1 and bits 0 and 1 to go
high in port 2.
A "B" specifies that the output format for the data is binary. Note
that this format is unavailable in the fast byte mode to keep the
output on a single 80-character line.
A "H" specifies that the output format for the data is hexadecimal.
A "Y" causes a byte-wide (8 bit) read of the port. This is the default
if no width is specified. See Example 1 above for a sample of a
byte-wide READ command.
A "W" causes a word-wide (16 bit) read for a pair of ports. Word-
wide operations are specified on even-numbered ports only, and
read the least significant 8 bits from the even port and the most
significant 8 bits from the following odd-numbered port.
Description: This command performs an asynchronous write to a
single port or a group of consecutive ports. No handshaking is
required for this operation. The command is primarily used to
write to asynchronous ports, but may be used to preset
synchronous ports to a known value before starting synchronous
operations.
