Detailed Description

Sanyo LC86k CPU core.

EvmuCpu is an EvmuPeripheral which implements all of the logic behind and provides an API for the CPU core.

In addition to managing normal program flow, it allows you to feed in individual instructions and then query for their decoded operands and opcode. It also provides a signal for when the PC changes, which can be used to implement breakpoints and instruction tracing.
