This command provides for a 6-byte BLOCK read of Telemetry values to improve bus utilization for poling by combining multiple READ functions into a single command, eliminating the need for multiple address and command code bytes.
Each Byte-pair within the READ_TELEMETRY block is ordered as a READ WORD pair with the low-byte first and high-byte second. The bytes are order as (Byte 0 through Byte 5):
Byte 0, Byte 1: READ_VOUT Low-Byte, READ_VOUT High-Byte
Byte 2, Byte 3: READ_IOUT Low-Byte, READ_IOUT High-Byte
Byte 4, Byte 5: READ_TEMP1 Low-Byte, READ_TEMP1 High-ByteReturn to Supported PMBus Commands.
