A pulse is presented on this LSTTL-compatible output when the HCTL-2032 / 2032-
SC internal counter overflows or underflows. The rising edge on this waveform may
be used to trigger an external counter.
This pin is used for internal testing. Tied it to ground or leave it floating for normal
operation.
These LSTTL-compatible tri-state outputs form an 8-bit output ports through which
the contents of the 32-bit position latch may be read in 4 sequential bytes. The MSB
is read first followed by the rest of the bytes with the LSB is read last.
