GIE: Global Interrupt Enable
N: Negative bit
This bit is set when the result of a byte or word operation is negative and cleared when the result is not negative.
Word operation: N is set to the value of bit 15 of the result Byte operation: N is set to the value of bit 7 of the result
Z: Zero bit
This bit is set when the result of a byte or word operation is 0 and cleared when the result is not 0.
C: Carry bit
This bit is set when the result of a byte or word operation
produced a carry and cleared when no carry occurred.
5.3.4 Constant Generation Registers CG1 and CG2
Six commonly-used constants are generated with the constant generator registers R2 and R3, without requiring
an additional 16-bit word of program code. The constants are selected with the source-register addressing modes
(As), as described in the table below:
The constant generator advantages are:
No special instructions required
No additional code word for the six constants
No code memory access required to retrieve the constant
The assembler uses the constant generator automatically if one of the six constants is used as an immediate
source operand. Registers R2 and R3, used in the constant mode, cannot be addressed explicitly; they act as source-
only registers.
5.3.5 General-Purpose Register R4 - R15
The twelve registers, R4-R15, are general-purpose registers. All of these registers can be used as data registers or
address pointers and can be used with byte or word instructions.
ELMOS Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
