40 / 45 page  Data Sheet ADIS16501 USER REGISTER DEFINITIONS analog.com Rev. B | 40 of 45 Firmware Revision (FIRM_REV) Table 114. FIRM_REV Register Definition Addresses Default Access Flash Backup 0x6C, 0x6D Not applicable R No Table 115. FIRM_REV Bit Definitions Bits Description [15:0] Firmware revision, binary coded decimal (BCD) format The FIRM_REV register (see Table 114 and Table 115) provides the firmware revision for the internal firmware. This register uses a BCD format where each nibble represents a digit. For example, if FIRM_REV = 0x0104, the firmware revision is 1.04. At the time of this data sheet release, FIRM_REV = 0x0200. Firmware Revision Day and Month (FIRM_DM) Table 116. FIRM_DM Register Definition Addresses Default Access Flash Backup 0x6E, 0x6F Not applicable R No Table 117. FIRM_DM Bit Definitions Bits Description [15:8] Factory configuration month, BCD format [7:0] Factory configuration day, BCD format The FIRM_DM register (see Table 116 and Table 117) contains the month and day of the factory configuration date. The FIRM_DM register, Bits[15:8] contain digits that represent the month of the factory configuration. For example, November is the 11th month in a year and is represented by Register FIRM_DM, Bits[15:8] = 0x11. The FIRM_DM register, Bits[7:0] contain the day of factory configu- ration. For example, the 27th day of the month is represented by Register FIRM_DM, Bits[7:0] = 0x27. At the time of this data sheet release, FIRM_DM = 0x1215. Firmware Revision Year (FIRM_Y) Table 118. FIRM_Y Register Definition Addresses Default Access Flash Backup 0x70, 0x71 Not applicable R No Table 119. FIRM_Y Bit Definitions Bits Description [15:0] Factory configuration year, BCD format The FIRM_Y register (see Table 118 and Table 119) contains the year of the factory configuration date. For example, the year, 2017, is represented by FIRM_Y = 0x2017. At the time of this data sheet release, FIRM_Y = 0x2023. Product Identification (PROD_ID) Table 120. PROD_ID Register Definition Addresses Default Access Flash Backup 0x72, 0x73 0x5FB5 R No Table 121. PROD_ID Bit Definitions Bits Description [15:0] Product identification = 0x5FB5 The PROD_ID register (see Table 120 and Table 121) contains the numerical portion of the device number (24,501). See Figure 41 for an example of how to use a looping read of this register to validate the integrity of the communication. Serial Number (SERIAL_NUM) Table 122. SERIAL_NUM Register Definition Addresses Default Access Flash Backup 0x74, 0x75 Not applicable R No Table 123. SERIAL_NUM Bit Definitions Bits Description [15:0] Lot specific serial number Scratch Registers (USER_SCR_1 to USER_SCR_3) Table 124. USER_SCR_1 Register Definition Addresses Default Access Flash Backup 0x76, 0x77 Not applicable R/W Yes Table 125. USER_SCR_1 Bit Definitions Bits Description [15:0] User defined Table 126. USER_SCR_2 Register Definition Addresses Default Access Flash Backup 0x78, 0x79 Not applicable R/W Yes Table 127. USER_SCR_2 Bit Definitions Bits Description [15:0] User defined Table 128. USER_SCR_3 Register Definition Addresses Default Access Flash Backup 0x7A, 0x7B Not applicable R/W Yes Table 129. USER_SCR_3 Bit Definitions Bits Description [15:0] User defined The USER_SCR_1 (see Table 124 and Table 125), USER_SCR_2 (see Table 126 and Table 127), and USER_SCR_3 (see Table 128 and Table 129) registers provide three locations for the user to store |
