Bit 0 – Reset/Halt/Sleep Interrupt Flag (IRR0): This flag can get set for three different reasons.
It can indicate that:
1. Reset mode has been entered after a SW (MCR0) or HW reset
2. Halt mode has been entered after a Halt request (MCR1)
3. Sleep mode has been entered after a sleep request (MCR5) has been made while in Halt mode.
The GSR may be read after this bit is set to determine which state RCAN-TL1 is in.
Important: When a Sleep mode request needs to be made, the Halt mode must be used
beforehand. Please refer to the MCR5 description and Figure 19.15 Halt Mode/Sleep Mode.
IRR0 is set by the transition from "0" to "1" of GSR3 or GSR4 or by transition from Halt mode to
Sleep mode. So, IRR0 is not set if RCAN-TL1 enters Halt mode again right after exiting from Halt
mode, without GSR4 being cleared. Similarly, IRR0 is not set by direct transition from Sleep
mode to Halt Request. At the transition from Halt/Sleep mode to Transition/Reception, clearing
GSR4 needs (one-bit time - TSEG2) to (one-bit time * 2 - TSEG2).
In the case of Reset mode, IRR0 is set, however, the interrupt to the CPU is not asserted since
IMR0 is automatically set by initialisation.
