General Release Specification

Interrupts

4.5.3 Serial Communications Interface Interrupt

Five different serial communications interface (SCI) interrupt flags that

cause an SCI interrupt whenever they are set and enabled. The interrupt

flags are in the SCI status register (SCSR), and the enable bits are in the

SCI control register 2 (SCCR2). Any of these interrupts will vector to the

same interrupt service routine, located at the address specified by the

contents of memory location $0FF2 and $0FF3. See Section 11. Serial

Communications Interface.

4.5.4 Core Timer Interrupt

Two different core timer (CTIMER) interrupt flags cause a CTIMER

interrupt whenever they are set and enabled. The interrupt flags and

enable bits are located in the CTIMER control and status register

(CTCSR). Any of these interrupts will vector to the same interrupt service

routine, located at the address specified by the contents of memory

location $0FF0 and $0FF1. See Section 12. Core Timer.
