Figure 5 describes the Register_0 write command sequence. Other information such as MIPI USID programming sequences, MIPI bus specifications, etc. can be referred to the MIPI Alliance Specification for RF Front-End Control Interface (RFFE), V1.10 (26 July 2011) and the subsequent versions. In the below timing figures, SA[3:0] is the slave address. A[4:0] denotes the register address. D[7:0] means the data. “P” is a parity bit.

Power On 1) Apply voltage supply - VDD 2) Apply logic supply - VIO 3) Wait 30μs or longer and then apply MIPI bus signals – SCL and SDA 4) Wait 25μs or longer after MIPI bus goes idle and then apply the RF Signal Power Off 1) Remove the RF Signal 2) Remove MIPI bus – SCL and SDA 3) Remove logic supply - VIO 4) Remove voltage supply - VDD VDD VIO ON ON CMD CMD START END RF ON RF OFF VIO OFF VDD OFF VDD 10us 10us VIO Slave State SHUTDOWN ACTIVE STARTUP 30us 25us SHUTDOWN No Operations During RF ON SDA,SCL RF Signal RF ON Figure 6 Power On and Off Sequence Notice  VIO can also be applied to the device before VDD or removed after VDD.  It is important not to send any SDA until a 10us or longer waiting time following the VDD and VIO startup to ensure corrective data transmission.  Operations of SDA or SCL are strictly prohibited during RF On period so as to prevent the device being damaged.  The minimum time between a power up and power down sequence (and vice versa) shall be 100us or longer.
