SAB-C161K-L16M SIEMENS [Siemens Semiconductor Group], SAB-C161K-L16M Datasheet - Page 23

• Manufacturer Part Number: SAB-C161K-L16M
• Description: 16-Bit CMOS Single-Chip Microcontroller
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

Special Function Registers Overview
The following table lists all SFRs which are implemented in the C161 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”.
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).
