10.12 Preprocessor Integer Arithmetic
You can declare a preprocessor DWORD variable, make arithmetic operations with it, and use it
in field and setting/parameter assignments.
Note: Arithmetic expressions are allowed only in numeric variable assignments. Some legal
expressions are.

x = y + 2

TX_PACKET ( Delay = (x+y)*7 )

TX_PACKET ( x + 12 )
Examples
Const TX_PAYLOAD_OFFSET = 16 * 8
Const "Some Hex Data" = 0xAABB
Main
{
x = 2
y = ( z = 12 ) + ( TX_PAYLOAD_OFFSET + 36 ) / 8
z = 0x1 << 5
s =
"Some Hex Data" # Constants may be used in operations.
x++
y--
z += ( x + y )
x = ( ( y & 0xFF ) >> 5 ) / 12
Send TX_PACKET ( Delay = x )
Send TX_PACKET
{
Endp = 0xEEEE
