INPUT PORT
In the following events, Data from the INPUT PORTs are broadcasted using the INPUT DATA packet:
Also, the following data are transmitted together with the data from INPUT PORTs:
The data from the OUTPUT PORTs are retransmitted (feed backed) to the bits that are configured as
OUTPUT PORTs. However, if bits PD7 – 4 are configured as FLAG OUTPUT, ”1” is transmitted to each
corresponding bit. Additionally, if the transmit trigger is configured as the external trigger, ”0” is transmitted
to the corresponding trigger input pin: PC0 or PD0.
No INPUT DATA packet is transmitted before the START TRANSMIT command is received from the host
(i.e., the transmission function is activated). Once the START TRANSMIT command is received, the
transmission of the INPUT DATA packet commences depending on the transmit trigger mode configured
through network using bits TXTRG3 - 0. For detailed information, see sections
Through Network and
Own token is received immediately after the START TRANSMIT command is received.
Own token is received after the transmit trigger is issued.
Own token is received immediately after the OUTPUT PORT command is received.
