Register Pointer Operations
Access to internal registers is accomplished via a pointer register. The pointer contains the address of the register affected by
register data write and read operations. Two register pointer operations are provided: Register Pointer Write, and Register Pointer
Read. Command and response information is shown in Table 20 .
6.5
Register Data Operations
Two register operations are provided: Register Write, and Register Read. In each case, the address of the affected register is
contained in the register pointer.
6.5.1
Register Write Command
The Register Write command format is shown in Table 20 . The least significant 8 bits of the Register Write command message
contain the data to be written to the register pointed to by the register pointer. The least significant 8 bits of the Register Write
response message contain the address of the register that was modified.
The write to the register is executed during the clock cycle immediately after CS is deasserted.
