Section 11 Multi-Function Timer Pulse Unit 2 (MTU2)
(3)
Interrupts TGIA_3 (at the crest) and TCIV_4 (at the trough) in channels 3 and 4 can be skipped up
to seven times by making settings in the timer interrupt skipping set register (TITCR).
Transfers from a buffer register to a temporary register or a compare register can be skipped in
coordination with interrupt skipping by making settings in the timer buffer transfer register
(TBTER). For the linkage with buffer registers, refer to description (c), Buffer Transfer Control
Linked with Interrupt Skipping, below.
A/D converter start requests generated by the A/D converter start request delaying function can
also be skipped in coordination with interrupt skipping by making settings in the timer A/D
converter request control register (TADCR). For the linkage with the A/D converter start request
delaying function, refer to section 11.4.9, A/D Converter Start Request Delaying Function.
The setting of the timer interrupt skipping setting register (TITCR) must be done while the
TGIA_3 and TCIV_4 interrupt requests are disabled by the settings of TIER_3 and TIER_4 along
with under the conditions in which TGFA_3 and TCFV_4 flag settings by compare match never
occur. Before changing the skipping count, be sure to clear the T3AEN and T4VEN bits to 0 to
clear the skipping counter.
(a)
Figure 11.67 shows an example of the interrupt skipping operation setting procedure. Figure 11.68
shows the periods during which interrupt skipping count can be changed.
