MEM.UnpackWord (FB prefix: memuw)

This function block of the ⇘ CAA_Memory.library will unpack the WORD “wValue“ and return the 2 bytes contained "byLowByte", "byHighByte" and the 16 bits "xBit0" .. "xBit15".

Input:

wValue

WORD

WORD to be unpacked

Output:

wLowByte	BYTE	Low byte of wValue
wHighByte	BYTE	High byte of wValue
xBit0	BOOL	Bit 0 of dwValue
xBit1	BOOL	Bit 1 of dwValue
xBit2	BOOL	Bit 2 of dwValue
xBit3	BOOL	Bit 3 of dwValue
xBit4	BOOL	Bit 4 of dwValue
xBit5	BOOL	Bit 5 of dwValue
xBit6	BOOL	Bit 6 of dwValue
xBit7	BOOL	Bit 7 of dwValue
xBit8	BOOL	Bit 8 of dwValue
xBit9	BOOL	Bit 9 of dwValue
xBit10	BOOL	Bit 10 of dwValue
xBit11	BOOL	Bit 11 of dwValue
xBit12	BOOL	Bit 12 of dwValue
xBit13	BOOL	Bit 13 of dwValue
xBit14	BOOL	Bit 14 of dwValue
xBit15	BOOL	Bit 15 of dwValue

Example:

wValue = 16#0102 = 2#00000001 00000010

->

byLowByte = 16#02

byHighByte = 16#01

xBit1,xBit8 = TRUE

remain bits = FALSE
