Program Flash is accessed one byte at a time via the
4-bit command, ‘1001’ (table read, post-increment).
The contents of memory pointed to by the Table Pointer
(TBLPTRU:TBLPTRH:TBLPTRL) are serially output on
PGD.

The 4-bit command is shifted in LSb first. The read is
executed during the next 8 clocks, then shifted out on
PGD during the last 8 clocks, LSb to MSb. A delay of
P6 must be introduced after the falling edge of the 8th
PGC of the operand to allow PGD to transition from an
input to an output. During this time, PGC must be held
low (see Figure 5-1). This operation also increments
the Table Pointer by one, pointing to the next byte in
program Flash for the next read.
This technique will work to read any memory in the
000000h to 3FFFFFh address space, so it also applies
to the reading of the ID and Configuration registers.
