26 / 34 page ![]() P9225-R Datasheet © 2018 Integrated Device Technology, Inc. 26 November 12, 2018 Table 20. Read Register – Die Temperature TDIE = (ADC_Die_Temp–1350)83 444 – 273 where ADC_Die_Temp = 12 bits from ADC_Die_Temp_H and ADC_Die_Temp_L. Address and Bit Register Field Name R/W Default Function and Description 0046HEX [7:0] ADC_Die_Temp_L R – 8 LSB of current die temperature in °C. 0047HEX [7:4] Reserved R 0HEX Reserved 0047HEX [3:0] ADC_Die_Temp_H R – 4 MSB of current die temperature in °C. Table 21. Read Register – Operating Frequency fOP= 64 ∗6000 OP_FREQ [15:0] Address and Bit Register Field Name R/W Default Function and Description 0048HEX [7:0] OP_FREQ[7:0] R – 8 LSB AC signal frequency on the coil. 0049HEX [7:0] OP_FREQ[15:8] R – 8 MSB AC signal frequency on the coil. Table 22. Command Register Address and Bit Register Field Name R/W Default Function and Description 004EHEX [7:6] Reserved R 0HEX Reserved. 004EHEX [5] Clear_Interrupt RW 0BIN If application processor sets this bit to "1," the P9225-R clears the interrupt pin. 004EHEX [4] Send Batt Charge status R 0BIN If the application processor sets this bit to "1," the P9225-R sends the battery charge status (see Batt_Charg_status in Table 15). 004EHEX [3] Send_End_Power_Transfer RW 0BIN If application processor sets this bit to "1," the P9225-R sends the End Power Transfer packet (defined in the EPT_Code register shown in Table 16) to the transmitter and then sets this bit to "0." 004EHEX [2] Reserved R 0BIN Reserved. 004EHEX [1] Toggle_LDO_On-OFF RW 0BIN If application processor sets this bit to "1,” the P9225-R toggles the LDO output once (from ON to OFF or from OFF to ON), and then sets this bit to “0.” 004EHEX [0] Reserved R 0BIN Reserved. |
