Timer functionality in sleep mode (CY8C20xx6A).

Last Updated: December 08, 2010

In CY8C20xx6A devices, when device is in sleep mode, can Timer1 and Timer2 wakeup the device?


The following interrupts can wakeup the device from sleep mode: 

  1. GPIO

  2. Sleep timer

  3. Timer0
  4. Vmonitor

  5. USB RST

  6. USB ACT

  7. 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.
