2.3.1 LOAD DATA FOR PROGRAM
MEMORY
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.

2.3.2 LOAD DATA FOR DATA MEMORY
Load data for data memory receives an 8-bit byte, and
readies it to be programmed into data memory at loca-
tion specified by the lower 7 bits of the PC. Though the
data byte is only 8-bits wide, all 16 clock cycles are
required to allow the programming module to reset
properly.
