2.4.1
Load data for program memory receives a 14-bit word,
and readies it to be programmed at the PC location.
See Figure 2-4 for timing details.
FIGURE 2-4:
2.4.2
Load data for data memory receives an 8-bit byte and
readies it to be programmed into data memory. Though
the data byte is only 8-bits wide, all 16 clock cycles are
required to allow the programming module to reset
properly.
