The EBC also controls accesses to resources connected to the on-chip LXBus. The
LXBus is an internal representation of the external bus and allows accessing integrated
peripherals and modules in the same way as external components.
The TwinCAN module is connected and accessed via the LXBus.

Central Processing Unit (CPU)
The main core of the CPU consists of a 5-stage execution pipeline with a 2-stage
instruction-fetch pipeline, a 16-bit arithmetic and logic unit (ALU), a 32-bit/40-bit multiply
and accumulate unit (MAC), a register-file providing three register banks, and dedicated
SFRs. The ALU features a multiply and divide unit, a bit-mask generator, and a barrel
shifter.

Based on these hardware provisions, most of the XC161’s instructions can be executed
in just one machine cycle which requires 25 ns at 40 MHz CPU clock. For example, shift
and rotate instructions are always processed during one machine cycle independent of
