Special Function Registers Overview
The following table lists all SFRs which are implemented in the C165 in alphabetical
order.
Bit-addressable
SFRs are marked with the letter “
b
” in column “Name”. SFRs within the
Extended SFR-Space
(ESFRs) are marked with the letter “
E
” in column “Physical
Address”. Registers within on-chip X-peripherals are marked with the letter “
X
” in column
“Physical Address”.
An SFR can be specified via its individual mnemonic name. Depending on the selected
addressing mode, an SFR can be accessed via its physical address (using the Data
Page Pointers), or via its short 8-bit address (without using the Data Page Pointers).
