In the Datasheet (Revision D, 16th Feb 2012) of STK15C88 in the chapter "Hardware Protect"
the following text passage ist shown:
When VCAP < VSWITCH, all externally initiated STORE operations and SRAM WRITEs are inhibited.
Now i have the following questions:
1.) I think that VCAP is the operating voltage at the device. I found no explanation about this
voltage in the whole datasheet. Am i right?
2.) I understand this protection mechanism as follows:
If an autostore operation is running, no writes from a processor are possible to the SRAM-
aerea of the device STK15C88. Is this right and what is the reaction of the device in this case?
3.) What happens if a write operation is done in the moment when Vcc (mentioned VCAP??)
passes Vswitch and so initiates an autostore operation while the write is still running?
Thanks for your answers!
