General purpose registers (GPRs)
The GPRs form the register bank that the CPU works with. This register bank may be
located anywhere within the internal RAM via the Context Pointer (CP). Due to the
addressing mechanism, GPR banks reside only within the internal RAM. All GPRs are bit-
addressable.
Table 65.
The first eight GPRs (R7...R0) may also be accessed bytewise. Other than with SFRs,
writing to a GPR byte does not affect the other byte of the respective GPR. The respective
halves of the byte-accessible registers have special names:
