The REGOUT control code allows for data to be
extracted from the device in ICSP mode. It is used to
clock the contents of the VISI register, out of the device,
over the PGDx pin. After the REGOUT control code is
received, the CPU is held Idle for 8 cycles. After these
8 cycles, an additional 16 cycles are required to clock the
data out (see Figure 3-3).
The REGOUT code is unique because the PGDx pin is
an input when the control code is transmitted to the
device. However, after the control code is processed,
the PGDx pin becomes an output as the VISI register is
shifted out.
