two questions on Byte Count for LPC Flash Writes

2006-01-28 by Jayasooriah

Hello,

N1: In the ECC section of the user manual, it is stated that flash can be 
written to in units of 16-bytes, aligned on any 16-byte boundary.

N2: In the ISP/IAP COPY commands documentation, it is stated that byte 
count must be one of 256, 512, 1024 or 4096.

Q1: N1+N2 implies that to update 16 bytes (on 16-byte boundary), one must 
read 256 bytes, modify 16 bytes at the appropriate offset, and then write 
256 bytes.  Is this correct?

Q2: What is the rational for what appears to be arbitrary limits on the 
values for byte counts in N2.

Thanks

Jaya
