Bits Description
The FIRM_Y register (see Table 114 and Table 115) contains the [15:0] User defined year of the factory configuration date. For example, the year, The USER_SCR_1 (see Table 120 and Table 121), USER_SCR_2 2017, is represented by FIRM_Y = 0x2017. (see Table 122 and Table 123), and USER_SCR_3 (see Table 124 and Table 125) registers provide three locations for users to store information. For nonvolatile storage, use the manual flash memory update command (Register GLOB_CMD, Bit 3, see Table 109), after writing information to these registers. Rev.
