11.10 Reading Code Memory
Reading from code memory is performed by executing
a series of TBLRD instructions and clocking out the data
using the REGOUT command. To ensure efficient
execution and facilitate verification on the programmer,
four instruction words are read from the device at a
time.
Table 11-10
reading code memory. In Step 1, the Reset vector is
exited. In Step 2, the 24-bit starting source address for
reading is loaded into the TBLPAG and W6 registers.
The upper byte of the starting source address is stored
to TBLPAG, while the lower 16 bits of the source
address are stored to W6.

reading (see
W7 is initialized, and four instruction words are read
from code memory and stored to working registers
W0:W5. In Step 4, the four instruction words are
clocked out of the device from the VISI register using
the REGOUT command. In Step 5, the internal PC is
reset to 0x100, as a precautionary measure, to prevent
the PC from incrementing into unimplemented memory
when large devices are being read. Lastly, in Step 6,
Steps 3-5 are repeated until the desired amount of
code memory is read.
