Synopsys ARC Local Timer with Interrupt Capabilities
|
|
|
|
- Found on all ARC CPUs (ARC700/ARCHS)
|
|
- Can be optionally programmed to interrupt on Limit
|
|
- Two identical copies TIMER0 and TIMER1 exist in ARC cores and historically
|
|
TIMER0 used as clockevent provider (true for all ARC cores)
|
|
TIMER1 used for clocksource (mandatory for ARC700, optional for ARC HS)
|
|
|
