Banking
The data memory is partitioned into four banks. Each bank contains General Purpose Registers
and Special Function Registers. Switching between these banks requires the RP0 and RP1 bits
in the STATUS register to be configured for the desired bank when using direct addressing. The
IRP bit in the STATUS register is used for indirect addressing.
Table 6-1:
Each Bank extends up to 7Fh (128 bytes). The lower locations of each bank are reserved for the
Special Function Registers. Above the Special Function Registers are General Purpose Regis-
ters. All data memory is implemented as static RAM. All Banks may contain special function reg-
isters. Some “high use” special function registers from Bank0 are mirrored in the other banks for
code reduction and quicker access.
Through the evolution of the products, there are a few variations in the layout of the Data Memory.
The data memory organization that will be the standard for all new devices is shown in
Figure
reduce the software overhead for context switching. The registers in bold will be in every device.
The other registers are peripheral dependent. Not every peripheral’s registers are shown,
because some file addresses have a different registers from those shown. As with all the figures,
tables, and specifications presented in this reference guide, verify the details with the device spe-
cific data sheet.
