PRODUCTION DATA.
The RREG command reads the contents of one or more device configuration registers. When the device is in read data continuous mode, an SDATAC command must be issued before the RREG command can be issued. The RREG command can be issued at any time. The RREG command is a two-byte command on DIN followed by the register data output on DOUT. The command is constructed as follows:
First byte: 001r rrrr, where r rrrr is the starting register address.
Second byte: 000n nnnn, where n nnnn is the number of registers to read – 1.
The 17th SCLK rising edge of the operation clocks out the MSB of the first register, as shown in Figure 43. However, because this command is a multibyte command, there are SCLK rate restrictions depending on how the SCLKs are issued; see Figure 1. CS must be low for the entire command.
