C-bus Interface (RIICa)
35.15 Event Link Function (Output)
The RIIC0 handles event output for the event link controller (ELC) corresponding to the following sources.
 Communication error/ communication event
 Receive data full
 Transmit data empty
 Transmit end
35.15.1 Interrupt Handling and Event Linking
The RIIC module produces four kinds of interrupt: transfer error (arbitration-lost detection, detection of NACK,
detection of timeout, or detection of a stop condition) event, receive data full, transmit data empty, and transmit end
interrupts detection of a start condition. Each of these has an enable bit to control enabling and disabling of the interrupt
signal. An interrupt request signal is output for the CPU when an interrupt source condition is satisfied while the setting
of the corresponding enable bit is enabled.
The corresponding event signals are sent to other modules via the ELC when the interrupt source conditions are satisfied,
regardless of the settings of the interrupt enable bits.
For details on interrupt sources, see
Table 35.6.
