Write Command

On write commands, the host can start to send data to SB201 after it has received the replied command byte. After SB201 has received the whole message, it will execute the command if it was understood and the PEC was correct. It will send an ACK back to the host after it has finished executing it. If the command was supported but the PEC wrong, a NACK is sent back. On all other errors nothing is sent back.

ACK is 0xFF and NACK is 0x00.
