6-4-2 Memory Area Code
6-4-3 Data Configuration
Flag or Bit Status (One Byte) 00: Bit is OFF (0)
Word Contents, PV (Two Bytes)
Each word/bit address specifies a specific bit or word. The rightmost two digits of
the address specify bit 00 to 15 (or 00 if not required), and leftmost four digits
specify the word address.
To obtain the corresponding address of the desired word or bit, add the data area
word address (hexadecimal) to the first address of the range of addresses used
for that data area in communications. For example, the address for word AR 13
is computed as follows:
The word address for AR 13 would thus be 049900 (the memory area code
would specify this as a word) and the address of bit 12 in AR 13 would be
04990C.
The memory area code specifies the data area being accessed and whether a
bit or word is being accessed, as shown below.
If the access size indicates a bit is being accessed, one byte of data will be read
or written. If the access size indicates a word is being accessed, two bytes of
data (one word) will be read or written.
The configuration of the types of data that can be read or written is shown below.
The number of bytes required for each type of data is also given.
01: Bit is ON (1)
Bit:
2. The memory area codes for the EM Area are as follows: codes 90 through
97 specify banks 0 through 7 and code 98 specifies the current bank.
