1-5 RR_STCH Command. Read STCH register value

The following diagram shows the timing diagram of reading data from the STCH register.

The DIN data in C1~C4 cycle is RR_STCH command code.

The DOUT data in C5 cycle is RC oscillator enable bit, D11 = ENOSC.

The DOUT data in C6 cycle is AD Range Select, D10 = AD_RANGE.

The DOUT data in C7~C9 cycle is Channel AB select, D9 – D7 = CHAB_SEL[2:0].

The DOUT data in C10~C12 cycle is Channel B select, D6 – D4 = CHB_SEL[2:0].

The DOUT data in C13~C16 cycles are MOSFET enable, D3 = M1_ENB, D2 = M2_ENB, D1 = M3_ENB, D0 = M4_ENB.
