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.
Table 5-8 shows the ICSP programming details for
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 register and W6
register. The upper byte of the starting source address
is stored in TBLPAG and the lower 16 bits of the source
address are stored in W6.
To minimize the reading time, the packed instruction
word format that was utilized for writing is also used for
reading (see Figure 5-7). In Step 3, the write pointer,
W7, is initialized. In Step 4, two instruction words are
read from code memory and clocked out of the device,
through the VISI register, using the REGOUT command.
Step 4 is repeated until the desired amount of code
memory is read.
