Table 6. When writing to Registers having Incremental Addresses, totally 1+n octets are clocked into the MICRF405.
Micrel
• Bring SEN low
• Use SCK and SIO to clock in the 1 + n octets
• Bring SEN high

Comments
7 bit = A6, A5, …A0 (A6 = MSB. A0 = LSB) (address of first byte to write to)
“0” for writing
n* 8 bits =
D7, D6, …D0 (D7 = MSB, D0 = LSB) (written to control reg. with address ”i”)
D7, D6, …D0 (D7 = MSB, D0 = LSB) (written to control reg. with address ”i+1”)
D7, D6, …D0 (D7 = MSB, D0 = LSB) (written to control reg. with address ”I+n-1”)
