1.2.6 In-Band Interrupt/Hot-Join NACK Causes the IBI/HJ Request to Be Canceled When a Bus Time-Out Occurs

When the bus time-out is enabled (BTOEN = 1) and an In-Band Interrupt/Hot-Join request is NACK'd by the controller, an unexpected behavior is observed. When the controller does not follow the NACK with a Stop and a bus time-out happens, the BTOIF bit is set as expected. However, alongside the BTOIF, the IBIEIF/HJEIF error bit is also set erroneously, which clears the IBIREQ/HJREQ bit.

Work around

None.
