3.2.2 SPECIAL FUNCTION REGISTER

The Special Function Registers are registers used by

the application to control the desired operation of

peripheral functions in the device. The registers asso-

ciated with the operation of the peripherals are

described in the appropriate peripheral chapter of this

data sheet.

3.2.3 GENERAL PURPOSE RAM

There are up to 80 bytes of GPR in each data memory

bank.

3.2.3.1 Linear Access to GPR

The general purpose RAM can be accessed in a

non-banked method via the FSRs. This can simplify

access to large memory structures. See Section 3.5.2

“Linear Data Memory” for more information.

3.2.4 COMMON RAM

There are 16 bytes of common RAM accessible from all

banks.
