From: Lucjan Bryndza <lbryndza....@icloud.com> The current implementation of timers does not work properly even in basic functionality. A counter configured to report an interrupt every 10ms reports the first interrupts after a few seconds. There are also no properly implemented count up an count down modes. This commit fixes bugs with interrupt reporting and implements the basic modes of the counter's time-base block.
