RDATA: Read Data
Description: Issue this command opcode after DRDY goes low to read the conversion result (in Stop Read Data
Continuous mode). See the Read Data Mode section for more details.
RREG: Read from Registers
Description: These opcode bytes read register data. The Register Read command is a two-byte opcode
followed by the output of the register data. The first byte contains the command opcode and the register address.
The second byte of the opcode specifies the number of registers to read
– 1.
First opcode byte: 0010 rrrr, where rrrr is the starting register address.
Second opcode byte: 0000 nnnn, where nnnn is the number of registers to read.
The 17th SCLK rising edge of the operation clocks out the MSB of the first register.
(1) CS may be tied low.

(OPCODE 1 = 0010 0000, OPCODE 2 = 0000 0001)
