8-bit microcontroller with on-chip CAN

7.2.1 MAIN RAM

Four 8-bit register banks occupy the lower RAM area,

• BANK 0: location 0 to 7

• BANK 1: location 8 to 15

• BANK 2: location 16 to 23

• BANK 4: location 24 to 31.

Only one of these banks may be enabled at the same time.

The next 16 bytes, locations 32 through 45, contains

128 directly addressable bit locations.

The stack can be located anywhere in the internal MAIN

RAM address space. The stack depth is only limited by the

internal RAM space available. All registers except the

program counter and the four 8-bit register banks reside in

the SFR address space.

7.3 External Data Memory

An access to external Data Memory locations higher than

255 will be performed with the MOVX @DPTR instructions

in the same way as in the 80C51 structure,

i.e. with P0 and P2 as data/address bus and P3.6 and P3.7

as Write and Read strobe signals.

Note that these external Data Memory locations cannot be

accessed with R0 or R1 as address pointer.
