7.5.5 7-segment decode (SEG(P))
SEG(P)
Function
(1) Decodes the data from 0 to F designated by the lower 4 bits of to 7-segment display data,
and stores at .
(2) If is a bit device, indicates the head number of the devices storing the 7-segment display
data; if it is a word device, indicates the number of the device storing the data.
Operation Error
(1) There are no operation errors associated with the SEG(P) instruction.
: Data to be decoded or head number of the devices where the data to be decoded is stored (BIN 16 bits)
: Head number of the devices where the decoding result will be stored (BIN 16 bits)
