Hi

Physically speaking, where are the reigisters in a PIC micro?

Hi

Physically speaking, where are the reigisters in a PIC micro?

The exact addresses depend on the particular chip. However, being that PICs
are Harvard Architecture, the program memory and data memory are two
separate entities. The registers, and special function registers (STATUS,
PORTA, PORTB, etc) reside in the data memory.

Okay, even in the question i implied i knew they were in the chip, now
what about answering what i didn't answer for myself in the question,
what about in terms of the other internal bits.

Each PIC datasheet shows the physical location of all onboard registers.

Really? I only see their location in memory space, not physical
space... though Microchip has some nice die photos in their fab, I
don't see any on their website.

Are onboard memory (register locations) not "physical" locations..?
I wasn't aware he was asking for a die photo.
