7.5.1.3.4 1-Byte I2C Read Command for 16-Bit Data

Figure 7-13 and Figure 7-14 show examples of 1-byte I2C read command supported by the TMAG5173-Q1. Select I2C_RD =01b to enable this mode. The command byte contains 7-bit secondary device address and a '1' at the R/W bit. In this mode, per MAG_CH_EN and T_CH_EN bits setting, the device will send 16-bit data of the enabled channels and the CONV_STATUS register data byte. If CRC is enabled, the device will send an additional CRC byte based off the CRC calculation of the command byte and the data sent in the current packet. When multiple channels are enabled, the sent data follows the T, X, Y, and Z sequence in the successive data bytes.

GUID-20210921-SS0I-QDXB-SC7Q-177HKQQZ0KJV-low.svg Figure 7-11 1-Byte I2C Read Command for 16-Bit Data With CRC Disabled, CRC_EN = 0b
GUID-20210921-SS0I-MF87-GLTB-8DCSTNFMQMCM-low.svg Figure 7-12 1-Byte I2C Read Command for 16-Bit Data With CRC Enabled, CRC_EN = 1b
Note: In the 1-byte read command for 16-bit data only up to 3 channels data can be sent when CRC is enabled. This restriction doesn't apply if CRC is disabled.
