Dears.

Our customer have used MB91F522FSCPMC-GSE1(CY91F522FSCPMC-GSE1) to develop HVAC controller for automotive.
All functionalities are fine but the level of sleep current of this MCU is rather higher than their limit (Under 1mA).
For prompt technical support, I tried to see the datasheet like CY91520 Series 32-bit FR81S Microcontroller.pdf on the cypress website to find out the detail description in which it shows state diagram or easy understandable description about how to implement sleep mode and electrical characteristic of sleep mode.
It only said there is a detail description of “ POWER CONSUMPTION CONTROL" in the hardware manual. but i couldn’t find it.

My question is
1.Is there anyone who knows how to implement sleep mode of MB91F522FSCPMC-GSE1(CY91F522FSCPMC-GSE1)  and where i can find POWER CONSUMPTION CONTROL" in the hardware manual.

Best regards,
Wonjin(Kevin) Han.
