ALARM REPORTING AND INTERRUPT SERVICING
Alarm and error conditions are reported at outputs and the RSR. Use of the RSR and error count registers
simplifies system error monitoring. The RSR can be read in one of two ways: a burst read does not
disturb the RSR contents; a direct read will clear all bits set in the RSR unless the alarm condition which
set them is still active. Interrupts are enabled via the RIMR and are generated whenever an alarm or error
condition sets an RSR bit. The host controller must service the transceiver in order to clear an interrupt
condition. Clearing the appropriate RIMR bit will unconditionally clear an interrupt.
