/*
Primitive PS/2 Library for AVR
==============================
Host side is only supported now.
Synchronous USART is used to receive data by hardware process
rather than interrupt. During V-USB interrupt runs, CLOCK interrupt
cannot interpose. In the result it is prone to lost CLOCK edge.
I/O control
-----------
High state is asserted by internal pull-up.
If you have a signaling problem, you may need to have
external pull-up resisters on CLOCK and DATA line.

General Description:
This module implements a function for debug logs on the serial line of the
AVR microcontroller. Debugging can be configured with the define
'DEBUG_LEVEL'. If this macro is not defined or defined to 0, all debugging
calls are no-ops. If it is 1, DBG1 logs will appear, but not DBG2. If it is
2, DBG1 and DBG2 logs will be printed.
A debug log consists of a label ('prefix') to indicate which debug log created
the output and a memory block to dump in hex ('data' and 'len').
