EMASK
Error mask. Enables certain error condition(s) to set the error bit (bit 5) in the
status register.
Syntax
EMASK [value]
value
You enable an error condition by specifying its decimal weight as the value
parameter. To enable more than one error condition, specify the sum of the
weights. The error conditions and their weights are:
