xxxx x001 Bitstream in mode. The bitstream is sent in via pin Funct_Test while the bitstream clock is sent via
CLK_pin. The output can be checked via the serial interface.
xxxx x010 Bistream out mode. The bitstream is sent out through pin SPD while the bitstream clock is sent
through pin SPC. The pin TEST_ST must be tied to 1.5V.
xxxx x011 Internal clock check mode. The decimation signal is sent out through pin SPD while the main clock
can be checked through pin SPC. The pin TEST_ST must be tied to 1.5V.
xxxx x100 Flash write mode
xxxx x101 Flash read mode
xxxx x11x Sensor trimming
AD(3:0) = 0101 CTRL_Reg2
This is the second control register. It has 8 bit whose function is summarized below.
Note: x means don't care value.
Note: default value after Power On Reset is 0110 0011
0xxx xxxx Delayed Synchronous Conversion reference coming from CLK_pin/FIFO_Low reading signal.
1xxx xxxx Low rate Delayed Synchronous Conversion reference signal.
x1xx xxxx Delayed Synchronous Conversion enabled.
xx1x xxxx Clip on. The result of the measuring chain is clipped when exceding the maximum/minimum limit.
xxx0 0xxx 8 bit output word length
xxx0 1xxx 16 bit output word length
xxx1 xxxx 32 bit output word length
xxxx x1xx Bypass the embedded IIR filter
xxxx xx0x Set the decimation factor to 16. 32 when the bit is 1.
xxxx xxx0 Set the sinc order to 2. 3rd order when the bit is 1.
AD(3:0) = 0110 PLL_PRESC_MULT
This register contain the division factor used in the PLL prescaler and the most significant bit of the PLL multi-
plication factor.
AD(3:0) = 0111 PLL_PRESC_MULT
This register contain the least significant bit of the PLL multiplication factor.
AD(3:0) = 1000 IIR_A0
This register contain the A0 coefficient used in the embedded IIR register.
AD(3:0) = 1001 IIR_A1
This register contain the A1 coefficient used in the embedded IIR register.
AD(3:0) = 1010 IIR_A2
This register contain the A2 coefficient used in the embedded IIR register.
AD(3:0) = 1011 IIR_B1
This register contain the B1 coefficient used in the embedded IIR register.
