11-3-16SV READ 2 –– R$
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), CNT, CNTR(12), or TTIM(87) instruction at the specified pro-
gram address in the user’s program. This can only be done with a program of
less than 10K.
