66 / 93 page  Data Sheet ADP1050 READ_DUTY_CYCLE The READ_DUTY_CYCLE command returns the duty cycle of the PWM output value in linear format. Table 60. Register 0x94—READ_DUTY_CYCLE Bits Bit Name/Function R/W Description [15:11] Exponent R 5-bit N value for linear format: X = Y × 2N. 5-bit twos complement fixed at 10110 (−10 decimal). [10:0] Mantissa R 11-bit twos complement Y value for linear format: X = Y × 2N. READ_FREQUENCY The READ_FREQUENCY command returns the switching frequency value in linear format. Table 61. Register 0x95—READ_FREQUENCY Bits Bit Name/Function R/W Description [15:11] Exponent R 5-bit twos complement N value for linear format: X = Y × 2N. [10:0] Mantissa R 11-bit twos complement Y value for linear format: X = Y × 2N. READ_PMBUS_REVISION The READ_PMBUS_REVISION command returns the PMBus version information. The ADP1050 supports PMBus Revision 1.2. Reading of this command results in a value of 0x22. Table 62. Register 0x98—READ_PMBUS_REVISION Bits Bit Name/Function R/W Description [7:4] Part1 revision R Compliant to PMBus specifications, part 1: 0010 = Revision 1.2. [3:0] Part2 revision R Compliant to PMBus specifications, part 2: 0010 = Revision 1.2. MFR_ID Table 63. Register 0x99—MFR_ID Bits Bit Name/Function R/W Description [7:0] MFR_ID R/W Reads/writes the ID information of the manufacturer, which can be saved in the EEPROM. MFR_MODEL Table 64. Register 0x9A—MFR_MODEL Bit Bit Name/Function R/W Description [7:0] MFR_MODEL R/W Reads/writes the model information of the manufacturer, which can be saved in the EEPROM. MFR_REVISION Table 65. Register 0x9B—MFR_REVISION Bit Bit Name/Function R/W Description [7:0] MFR_REVISION R/W Reads/writes the revision information of the manufacturer, which can be saved in the EEPROM. IC_DEVICE_ID Table 66. Register 0xAD—IC_DEVICE_ID Bit Bit Name/Function R/W Description [15:0] IC_DEVICE_ID R Reads the IC device ID (default value = 0x4151). IC_DEVICE_REV Table 67. Register 0xAE—IC_DEVICE_REV Bits Bit Name/Function R/W Description [7:0] IC_DEVICE_REV R Reads the IC revision information. The value is 0x20 in the current silicon. Rev. A | Page 65 of 92 |
