Mnemonic: SetGPRMMD

Hex Code:4300000S00RR0000   unconditional, indirect
43M0000S00RRXXYY   M=1-7, Compare register XX to register YY, indirect
430K000S00RRHHLL   unconditional, indirect, K=1,4-7 Set then Link
5300SSSS00RR0000   unconditional, direct
53M0SSSS00RRXXYY   M=1-7, Compare register XX to register YY, direct
530KSSSS00RRHHLL   unconditional, direct, K=1,4-7 Set then Link
Action:The SetGPRMMD sets a GPRM value and mode (counter or register).
A register in counter mode increments once per second.
In all forms the destination GPRM number is in the lower 4 bits of "RR" (byte 5). Bit 7 of "RR" determines the mode, 0=register mode, 1=counter mode.
The indirect form uses the value in the GPRM register indicated by "S" (lower nibble of byte 3).
The direct form uses "SSSS" (bytes 2&3) as the value.
If "K" is 1, 4, 5, 6, or 7 the Set is followed by a link command.
Order:If a compare is specified, it is performed first. If the condition is met the SetGPRMMD is executed.
Comments:The command can be conditional or be combined with a link command, but not both.
The source and destination register may be the same, used for changing the mode only.
MOV is the only allowed operator of a set command with a GPRM in counter mode as the target.

Moperation
1RegX & RegYBCBitwise compare, the two operands are anded, if the result is non-zero the condition is true
2RegX == RegYEQIf the two operands are equal the condition is true
3RegX != RegYNEIf the two operands are not equal the condition is true
4RegX >= RegYGEIf RegX is greater than or equal to the right operand the condition is true
5RegX > RegYGTIf RegX is greater than the right operand the condition is true
6RegX <= RegYLEIf RegX is less than or equal to the right operand the condition is true
7RegX < RegYLTIf RegX is less than the right operand the condition is true
