The REGOUT control code allows for data to be extracted
from the device in ICSP mode. It is used to clock the con-
tents of the VISI register out of the device over the
PGEDx pin. After the REGOUT control code is received,
the CPU is held Idle for eight cycles. After these eight
cycles, an additional 16 cycles are required to clock the
data out (see

The REGOUT code is unique because the PGEDx pin is
an input when the control code is transmitted to the
device. However, after the control code is processed,
the PGEDx pin becomes an output as the VISI register
is shifted out.

The device will latch input PGEDx data on
the rising edge of PGECx and will output
data on the PGEDx line on the rising edge
of PGECx. For all data transmissions, the
Least Significant bit (LSb) is transmitted
first.
