Start Up Time on ADuC7020

The power up time for the core on the 7020 according to the datasheet is 300ms (CD = 0). Is this time defined as the time taken for the Firmware to start executing. My application is running at CD = 1. Does the power up time remain the same @ 20.89 Mhz.

 

There is also a internal POR Reset chip which holds the chip in reset for 128ms.

 

So at startup, if the processor is supplied with power and the chip is released from reset at the same time, does it take 128ms + 300ms for initialization?
