P Notes: 1. All serial PD data are not protected. 0: Serial data, “driven Low”, 1: Serial data, “driven High”
2. Byte72 is manufacturing location code. (ex: In case of Japan, byte72 is 4AH. 4AH shows “J” on ASCII
code.)
3. Bytes 95 through 98 are assembly serial number.
r ^{4. All bits of 99 through 127 are not defined (“1” or “0”).}
oduct ^{5. These specifications are defined based on component specification, not module.}
