As an example, the following code may be used in the user program:
// Read complete
// Get the LSW value
Address% = BaseAddress% + 5
LSW% = #Address%
// Get the MSW value
Address% = BaseAddress% + 6
MSW% = #Address%
Value% = (LSW% & 0x0000FFFF) | ((MSW% << 16) & 0xFFFF0000)
// Correct for 16bit -ive values
IF Bit32% = 0 THEN
// 16 bit
IF Value%.15 = 1 THEN
// Correct for negative number
Value% = Value% - 65536
ENDIF
ENDIF
BaseAddress% is the parameter specified in S.02.036.
Bit32% specifies the source parameter as 16-bit or 32-bit (0 = 16-bit. 1 = 32-bit).
