12.3
A 80C51 CPU Interface connects the PeliCAN to the
internal bus of an 80C51 microcontroller. Special Function
Registers, allows a smart and fast access to the PeliCAN
registers and RAM area. Because of the big address range
to be supported, an indirect pointer based addressing is
12.3.1
Via the five Special Function Registers CANADR,
CANDAT, CANMOD, CANSTA and CANCON the CPU
has access to the PeliCAN Block. Note that CANCON and
CANSTA have different registers mapped depending on
the direction of the access.

included allowing a fast register access with address
autoincrement mode. This reduces the needed number of
Special Function Registers to an amount of 5.
The PeliCAN registers may be accessed in two different
ways. The most important registers, which should support
software polling or are controlling major CAN functions are
accessible directly as separate SFRs. Other parts of the
PeliCAN Block are accessible using an indirect pointer
mechanism. In order to achieve a high data throughput
even if the indirect access is used, an address
auto-increment feature is included here.
