Question: In CY8C20xx6A devices, when device is in sleep mode, can Timer1 and Timer2 wakeup the device?
Answer:
The following interrupts can wakeup the device from sleep mode:
- GPIO
- Sleep timer
- Timer0
- Vmonitor
- USB RST
- USB ACT
- I2C
Timer1 and Timer2 do not work in sleep mode. Hence,in sleep mode they cannot generate interrupt ,nor can they wakeup the device.
In deep sleep mode,only GPIO interrupt works.
