Table 6-21 Bit Descriptions – Serial Number Registers
Bit Field Name Access Reset Description
7:0 serialNumber[n] RO/RW Serial Number byte N. The serial number returned in the Serial Number string descriptor at string index 1. The default value of these registers is set by TI. When customSernum is 1, these registers can be overwritten by EEPROM contents or by an SMBus host.
