6.1.3 SPI Read Timing (Burst Mode)
Burst mode access of read data is supported using a “Burst Read Command” by writing 0x00 in
BURST_CMD (BURST [0x00(W0)] bits[7:0]). In burst mode, ND flag/EA flag, temperature sensor value,
3-axis gyroscope sensor value, 3-axis acceleration sensor value, GPIO, etc. are consecutively sent as a
response. The response format for the burst read output data is configured by register setting in
BURST_CTRL1 [0x0C(W1)] and BURST_CTRL2 [0x0E(W1)]. Please refer to 6.3 Data Packet Format
for the response format.
