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.
