3.1.2.1
Load Data
After receiving this command, the device will clock in
14 bits as a “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 3-2:
LOAD DATA COMMAND (PROGRAM/VERIFY)
3.1.2.2
Read Data
After receiving this command, the chip will transmit
data bits out of the memory currently accessed starting
with the second rising edge of the clock input. The RB0
pin will go into Output mode on the second rising clock
edge and it will revert back to Input mode (high-imped-
ance) after the 16th rising edge. Because this is a 12-bit
core, the two MSbs will read as ‘1’. A timing diagram of
this command is shown in Figure 3-3.
