Name
Register Description (DATA3: This register selects the transmit trigger in FLAG OUTPUT.)
TXTRG3 - 0
The trigger condition to send the INPUT DATA packet is configured. The transmit trigger is enabled after
receiving the START TRANSMIT command.
Receiving the OUTPUT DATA packet:
A single transmit trigger is generated after receiving the OUTPUT DATA packet that is destined for this
node or broadcasted is received. The INPUT DATA packet is transmitted after receiving the token (i.e., the
token destined for this node).
Receiving the OUTPUT DATA packet or expiring on-chip timer:
A single transmit trigger is generated after either receiving the OUTPUT DATA packet that is destined for
this node or broadcasted, or expiring on-chip timer. The INPUT DATA packet is then transmitted after
receiving the token.
This on-chip timer is cleared by an of three events: receiving the START TRANSMIT command; receiving
the INITIALIZE OUTPUT PORT command; or transmitting an INPUT DATA packet after receiving a data
packet.
