Code memory 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 loaded into the
table latch and then serially output on SDATA.

Step 1: Set table pointer.
Step 2: Read memory into table latch and then shift out on SDATA, LSb to MSb.

LSb
The 4-bit command is shifted in LSb first. The table
read is executed during the next 8 clocks, then shifted
out on SDATA during the last 8 clocks, LSb to MSb. A
delay of P6 must be introduced after the falling edge of
the 8th SCLK of the operand to allow SDATA to transi-
tion from an input to an output. During this time, SCLK
must be held low (see Figure 4-1). This operation also
increments the table pointer by one, pointing to the next
byte in code memory 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.
