32 / 46 page ![]() P9221-R3 Datasheet © 2017 Integrated Device Technology, Inc. 32 October 20, 2017 Address and Bit Register or Bit Field Name R/W Default Function and Description 0038HEX [1] VRECT_OV_INT_EN RW 1BIN “0” disables the INT_VRECT_OV interrupt. "1" enables the interrupt. 0038HEX [0] OC_Limit_Status_INT_EN RW 1BIN “0” disables the INT_OC_Limit_Status interrupt. "1" enables the interrupt. 0039HEX [7:0] Reserved RW 00HEX Table 17. Battery Charge Status Address and Bit Register or Bit Field Name R/W Default Function and Description 003AHEX [7:0] Batt_Charg_status R/W 00HEX The application processor loads the battery charge status in this register. This value is sent to the transmitter when bit 4 of register 004EHEX is set to “1.”[a] [a] The firmware only forwards the data from the application processor to transmitter. Table 18. End Power Transfer The application processor initiates the End Power Transfer (EPT). Address and Bit Register or Bit Field Name R/W Default Function and Description 003BHEX [7:0] EPT_Code R/W 00HEX EPT_Code sent to transmitter. Table 19. Read Register – Output Voltage VOUT = ADC_VOUT ∗ 6 ∗ 2.1 4095 Address and Bit Register or Bit Field Name R/W Default Function and Description 003CHEX [7:0] ADC_VOUT [7:0] R 00HEX 8 LSB of VOUT ADC value. 003DHEX [7:4] Reserved R 0HEX Reserved. 003DHEX [3:0] ADC_VOUT [11:8] R 0HEX 4 MSB of VOUT ADC value. Table 20. Read Register – VRECT Voltage VRECT = ADC_VRECT ∗ 10 ∗ 2.1 4095 Address and Bit Register or Bit Field Name R/W Default Function and Description 0040HEX [7:0] ADC_VRECT [7:0] R – 8 LSB of VRECT ADC value. 0041HEX [7:4] Reserved R 0HEX Reserved. 0041HEX [3:0] ADC_VRECT [11:8] R – 4 MSB of VRECT ADC value. |
