PRODUCTION DATA.
The RREG command is used to read single- or multiple-register data. The command consists of a two-byte opcode argument, followed by the output of register data. The first byte of the opcode includes the starting address, and the second byte specifies the number of registers to read minus one.
First command byte: 001r rrrr, where rrrrr is the starting address of the first register.
Second command byte: 000n nnnn, where nnnnn is the number of registers to read minus one.
Starting with the 16th falling edge of SCLK, the register data appear on DOUT. Read the data on the 17th SCLK rising edge.
The RREG command is illustrated in Figure 68.
A delay of 24 fCLK cycles is required between each byte transaction.
