dsPIC30F Flash Programming Specification
11.2.2
REGOUT SERIAL INSTRUCTION
EXECUTION
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 PGD pin. Once the REGOUT control code is
received, eight clock cycles are required to process the
command. During this time, the CPU is held idle. After
these eight cycles, an additional 16 cycles are required
to clock the data out (see Figure 11-3).
The REGOUT instruction is unique because the PGD
pin is an input when the control code is transmitted to
the device. However, once the control code is
processed, the PGD pin becomes an output as the VISI
register is shifted out. After the contents of the VISI are
shifted out, PGD becomes an input again as the state
machine holds the CPU idle until the next 4-bit control
code is shifted in.
Note:
Once the contents of VISI are shifted out,
the dsPIC DSC device maintains PGD
as an output until the first rising edge of
the next clock is received.
