Registers

Standard Functions

These are the standard functions for managing 8- to 32-bit registers:

Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances.	Description
rol	Rotate bits of a register to the left.
ror	Rotate bits of a register to the right.
shl	Shift bits of a register to the left.
shr	Shift bits of a register to the right.

Advanced Function

This is the advanced function for register manipulation:

Function	Description
MBshift	Multi-byte shift / rotate.

Bit-to-Bit Functions

These functions enable bit-to-bit operations on a 8- to 32-bit integers:

Function	Description
and_mask	Performs a bit-to-bit Boolean AND between two integer values.
not_mask	Performs a bit-to-bit Boolean negation of an integer value.
or_mask	Performs a bit-to-bit Boolean OR between two integer values.
xor_mask	Performs a bit to bit exclusive OR between two integer values.

Pack / Unpack Functions

These functions enable pack / unpack 8-, 16-, and 32-bit registers:

Function	Description
HiByte	Get the highest byte of a word.
HiWord	Get the highest word of a double word.
LoByte	Get the lowest byte of a word.
LoWord	Get the lowest word of a double word.
MakeDWord	Builds a double word as the concatenation of two words.
MakeWord	Builds a word as the concatenation of two bytes.
PACK8	Pack bits in a byte.
UNPACK8	Extract bits from a byte.

Bit Access

These functions provide bit access in 8- to 32-bit integers:

Function	Description
SetBit	Set a bit in an integer register.
TestBit	Test a bit of an integer register.
