Section 10 16-Bit Integrated Timer Unit (ITU)
10.4.9
The ITU outputs from channels 3 and 4 can be disabled by bit settings in TOER or by an external
trigger, or inverted by bit settings in TOCR.
Timing of Enabling and Disabling of ITU Output by TOER
In this example an ITU output is disabled by clearing a master enable bit to 0 in TOER. An
arbitrary value can be output by appropriate settings of the data register (DR) and data direction
register (DDR) of the corresponding input/output port. Figure 10.54 illustrates the timing of the
enabling and disabling of ITU output by TOER.
