2.3.3.2 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
shown in Figure 2-4.

2.3.3.3 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 (hi-impedance) after the
16th rising edge.
If the program memory is code protected (CP
= 0), the
data is read as zeros.
