[Description] • Transmits the total capacity of the NV bit-image memory (number of bytes in the memory
area).
Hexadecimal Decimal Amount of data
Header 37H 55 1 byte
Flag 30H 48 1 byte
Data 30H – 39H 48 – 57 1 – 8 bytes
NUL 00H 0 1 byte
• The data describing total capacity is converted to character codes corresponding to decimal
data, then transmitted from the MSB.
• The data length is variable.
• The total capacity of the NV user memory is selectable as any one of these: [0, 64K, 128K,
192K, 256K, 320K, 384K] bytes with GS ( E. The default value is 384KB.
