/**
* Created by PIC32F_USER on 28/07/2017.
*
* Murax is a very light SoC which could work without any external component.
* - ICE40-hx8k + icestorm => 53 Mhz, 2142 LC
* - 0.37 DMIPS/Mhz
* - 8 kB of on-chip ram
* - JTAG debugger (eclipse/GDB/openocd ready)
* - Interrupt support
* - APB bus for peripherals
* - 32 GPIO pin
* - one 16 bits prescaler, two 16 bits timers
* - one UART with tx/rx fifo
