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').
