1. If both sides choose “Multi-port Device” or “Single-Port Device”, they exchange random numbers, and the side with the higher
number prevails.

If bit 9.11 = 1, this node must be the master.
If bit 9.11 = 0, this node must be the slave.
Bit 9.11= 0 is the default state. By default, bit 9.11 is not used.
Bit 9.10
Bit 9.10 is used only when bit 9.12 = 0. The initial state of bit 9.10 is set by the Master/Slave
configuration ball.
If bit 9.10 = 1, this node should be master.
If bit 9.10 = 0, this node should be slave.
Configuring Master/Slave in Hardware
The Master/Slave ball sets the default state of bit 9.10, which by default is the bit used to determine
whether this node is a master or a slave. If the Master/Slave ball is High, the device indicates that
it wants to be the master; if Low, the device indicates that it wants to be a slave.
Resolution of the Master/Slave Relationship
The multi-port and single-port settings guarantee resolution of the Master/Slave relationship, but
not a specific outcome. If both sides choose the same setting, a winner is randomly picked. In
contrast, the manual settings result either in the specified setting or a deadlock. Manual settings
take precedence over single-port and multi-port settings. Identical manual settings result in a
deadlock. Identical single-port or multi-port settings are resolved by a random number. These
relationships are summarized in
