Registers

All Register Functions (Alphabetically)

Name	Description
and_mask	Performs a bit-to-bit Boolean AND between two integer values.
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.
MBShift	Multi-byte shift / rotate.
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.
Pack8	Pack bits in a byte.
rol	Rotate bits of a register to the left.
ror	Rotate bits of a register to the right.
SetBit	Set a bit in an integer register.
shl	Shift bits of a register to the left.
shr	Shift bits of a register to the right.
TestBit	Test a bit of an integer register.
Unpack8	Extract bits from a byte.
xor_mask	Performs a bit to bit exclusive OR between two integer values.

This is the advanced function for register manipulation:

Name	Description
MBShift	Multi-byte shift / rotate.

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

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

These functions enable bit-to-bit operations from 8-bit to 32-bit integers:

Name	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.

These functions enable pack / unpack from 8-bit to 32-bit integers:

Name	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.

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

Name	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.
