LPC804 IAP stack usage

[johan_forslof]

What is the maximum stack space usage of the IAP programming functions? Section 4.3.7 of UM11065 rev 1.3 states the stack usage of ISP but does not list IAP usage.

We have measured 140 bytes but need to know the upper bound to determine how much to memory reserve to guarantee that no future ROM revisions or untested cases cause a stack overflow in our application.

Thank you in advance for your assistance.

Hi Johan,

You are right the stack usage of IAP is not documented.I checked we currently don't have this data.

I suggest you reserving 148bytes stack to IAP . this should enough.

Have a great day,
Jun Zhang
