7.3.11 VOUT_MODE (Address = 20h)

VOUT_MODE is shown in Figure 7-17 and described in Table 7-20.

Return to the Summary Table.

Write Transaction: N/A
Read Transaction: Read Byte
Data Format: unsigned binary (1 byte)
NVM Back-up: No
Updates: N/A The data byte for the VOUT_MODE command sets the data format for VOUT related commands. Data Validity: Attempts to write the VOUT_MODE command are considered as invalid data or unsupported data (ivd) and the device responds as described in the IVD bit in STATUS_CML.

BitFieldTypeResetDescription
7:5VOUT_MODE[2:0]R4h Bit 2 value of 1 indicates relative data format for VOUT related commands, such as VOUT_OV_FAULT_LIMIT and VOUT_UV_FAULT_LIMIT. Bits 1:0 indicate linear format (ULINEAR16, SLINEAR16)
4:0VOUT_EXPONENT[4:0]R17h Specifies the exponent to use with output voltage related commands in two's complement format. Value is fixed at -9 (1.953mV/LSB).
