Note 2: Writing to the lower byte of timer register 2 (TC2DRL), the comparison is inhibited until the upper byte
Note 3: Set the mode and source clock when the TC2 stops (TC2S = 0).
Note 4: Values to be loaded to timer register must satisfy the following condition.
Note 5: TC2CR are write-only registers and must not be used with any of the read-modify-write instructions.
Note 6: When STOP mode is started, timer counter is stopped and cleared. Set TC2S to “1” after STOP mode is
