• BURST_CTRL2 [0x0E(W1)] = 0x0000: All TEMP, angle rate, and acceleration output are 16-bit.
In the above case, a data output rate of 2000Sps is supported.
(4) For SPI and 16-bit output:
• SPI Interface Transmission Setting: FSCLK=1MHz and tSTALL=24us for normal mode
• DOUT_RATE = 0x01 of SMPL_CTRL [0x04(W1)] bit [15:8]: 2000Sps
• BURST_CTRL1 [0x0C(W1)] = 0xF006: FLAG, TEMP, angle rate, acceleration, GPIO, and COUNT output
• BURST_CTRL2 [0x0E(W1)] = 0x0000: All TEMP, angle rate, and acceleration output are 16-bit.
In the above case, a data output rate of 2000Sps is supported.
