C163-16F
Special Function Registers Overview
The following table lists all SFRs which are implemented in the C163-16F 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 (SSP) 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).
