+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').
