● When conversion control "EN" = 1 or "EN↑" ( P instruction) has a transition from 0 to 1, will convert N+1
number of nibbles (A nibble is comprised by 4 successive bits, so B0~B3 of S form nibble 0, B4~B7 form
nibble 1, etc...)within S to 7-segment code, and store the code into a low byte of D (High bytes does not
change). The 7 segment within D are put in sequence, with "a" segment placed at B6, "b" segment at
B5, .... ,"g" segment at B0. B7 is not used and is fixed as 0. For details please refer the "7-segment code
and display pattern table" shown in page 9-31.
● Because this instruction is limited to 16 bits, and S only has 4 nibbles (NB0~NB3), the effective range of N
is 0~3. Beyond this range, will set the N value flag error "ERR" to 1, and does not carry out this instruction.
● Care should be taken on total nibbles to be converted is N+1. N=0 means one digit to convert, N=1 means
two digits to convert etc…
● When using the FATEK 7-segment expansion module(FBs-7SG) and the FUN84 (7SEG) handy instruction
for mixing decoding and non-decoding application, FUN59 and FUN84 can be combined to simplify the
program design.(Please refer the example in chapter 16)
