BQ33100: MAC SBS Command Frame Sequence

Part Number: BQ33100

Hello, 

I want to Write MAC command to BQ33100,

1. for Lifetime and Capacitor Balancing Enable (0x0021) the sequence will be:

Write Frame:  Slave Address(0x16) => MAC (0x00) => SBS cmd (0x0021)

Write Frame:  Slave Address(0x16) => MAC (0x00) => DATA 0x01 / 0x00

2. for rest of the  MAC commands as there is no data part present, the sequence will be:

Write Frame:  Slave Address(0x16) => MAC (0x00) => SBS cmd (0x0024)

--

as per my understanding; for part 2, we just need to write the command into MAC(0x00) and the action will take place in BQ33100; which is not the case for part 1 , there I have to perform separate i2c write transaction to load the action data into BQ33100

is this understanding correct? 

Thanks.
