Diagnostic Mode
Diagnostic mode allows node number #31
The Diagnostic mode is set by setting the nDIAG pin to 0. The Diagnosis mode pin should be set only on
the node with largest node number (#n) in the network; on the other nodes it should be tied to 1.
W receiving a packet from node number #31, CircLink latches the last MSB (bit 7) of the last byte and
outputs it to the external output, FLASHO. This function is effective regardless of the nDIAG pin status,
and enables node #31
output FLASHO stays in high-impedance until a packet is received.
