MEM_DATA_LSB:
The MEM_DATA_LSB represents either: (1) the least significant 16 bits of the
data to be written to internal memory or (2) the least significant 16 bits of the
read data resulting from the previous read operation. The read data is not
valid until after the MEM_BUSY bit has been cleared.
MEM_DATA_MSB:
The MEM_DATA_MSB represents either: (1) the most significant 16 bits of
the data to be written to internal memory or (2) the least significant 16 bits of
the read data resulting from the previous read operation. The read data is not
valid until after the MEM_BUSY bit has been cleared.
The actual memory data structure is shown in Table 8 through Table 14.
Group Configuration Record Memory Area
The group configuration record area is located in the RIPP configuration memory.
There are 4 group configuration records that contain the PM programmed
configuration data for the corresponding groups. Each record is 16 words deep
by 32 bits wide, and is addressed by the group tag number.
MEM_ADDR = Area_base_address + Group_tag * 0x10 + Word Offset
