SV (Response)
The constant SV is returned.
Note 1. The instruction specified under "Name" must be in four characters.
2. If the same instruction is used more than once in a program, only the first one
will be read.
3. Use this command only when it is definite that a constant SV has been set.
4. The response end code will indicate an error (16) if the SV wasn't entered as
a constant.
Reads the constant SV or the word address where the SV is stored. The SV that
is read is a 4-digit decimal number (BCD) written as the second operand for the
TIM, TIMH(15), TIML(––), TMHH(––), CNT, or CNTR(12) instruction at the spe-
cified program address in the user's program. This can only be done with a pro-
gram of less than 10K.
