TMD ... Timer Mode
Timer 2 can be used in two different modes of operation.
0: Count Down Timer.
An interrupt is generated only once after a time period of 1 ... 63 ms.
1: Periodic Timer.
An interrupt is periodically generated every 1 ... 63 ms (see CNT).
CNT ... Timer Counter
0: Timer off.
1 ... 63:Timer period = 1 ... 63 ms
By writing ’0’ to CNT the timer is immediately stopped. A value different from that
determines the time period after which an interrupt will be generated.
If the timer is already started with a certain CNT value and is written again before an
interrupt has been released, the timer will be reset to the new value and restarted again.
An interrupt is indicated to the host in AUXI.TIN2.
Note: Reading back this value delivers back the current counter value which may differ
from the programmed value if the counter is running.
