20.3.4.1.10 Write Control Register (WCREG)
The operand (longword) data is written to the specified control register. The write alters all 32 register bits.
Command Sequence:
Operand Data:
Two operands are required for this instruction. The first long operand selects the register to which the
operand data is to be written. The second operand is the data.
Result Data:
Successful write operations return a $FFFF. Bus errors on the write cycle are indicated by the assertion of
bit 16 in the status message and by a data pattern of $0001.
