Entering Programming Mode
Depending on the MODE settings, DATA is latched in different internal registers.
Table 22-2.
When MODE is equal to CMDE, then a new command (strobed on DATA[15:0] signals) is stored
in the command register.
Table 22-3.
Note:
The following algorithm puts the device in Parallel Programming Mode:
