2.4.3.1 Load Data For Program Memory
After receiving this command, the chip will load in a
14-bit “data word” when 16 cycles are applied, as
described previously. Because this is a 12-bit core, the
two MSbs of the data word are ignored. A timing
diagram for the Load Data command is shown in
Figure 2-3.

2.4.3.2 Read Data From Program Memory
After receiving this command, the chip will transmit
data bits out of the program memory (user or
configuration) currently addressed, starting with the
second rising edge of the clock input. The data pin will
go into Output mode on the second rising clock edge,
and it will revert to Input mode (high-impedance) after
the 16th rising edge. Because this is a 12-bit core, the
two MSbs of the 14-bit word will be read as ‘1’s.
If the program memory is code-protected (CP
= 0),
portions of the program memory will be read as zeros.
See Section 4.0 “Code Protection” for details.
