WTOB(P ),BTOW( P)
Function
WTOB
(1) Dissociates n-bytes of the 16-bit data stored into the area starting from the device number
designated by , and stores them following the device designated by .
For example, if n 5, data through the lower 8 bits of to ( +2) would be stored from (
to +4).
: Head number of the devices where data to be dissociated/linked in byte units is stored (BIN 16 bits)
: Head number of the devices where the result of dissociated/linking in byte units will be stored (BIN 16 bits)
n : Number of byte data to be dissociated/linked (BIN 16 bits)
