This is a simple state. It loads to the CP2200/1 a packet containing an ASCII "I" in the first byte and padding (zeros) in all remaining bits. The CP2200/1 may handle padding itself; this will have to be verified in the data sheet. After the transmission is complete, the block writes a 010 to the state register.
This is a simple state. It loads to the CP2200/1 a packet containing an ASCII "I" in the first byte and padding (zeros) in all remaining bytes (minimum size of data is 46 bytes, so there needs to be 45 bytes of padding). After the transmission is complete, the block writes a 010 to the state register.
