Multifunction Timer Pulse Unit (MTU) Rev.5.00 Sep. 27, 2007 Page 252 of 716 REJ09B0398-0500 Table 10.13 MTU Interrupt Sources Channel Interrupt Source Description DMAC Activation Priority* 0 TGI0A TGR0A input capture/compare-match Yes High TGI0B TGR0B input capture/compare-match No TGI0C TGR0C input capture/compare-match No TGI0D TGR0D input capture/compare-match No TCI0V TCNT0 overflow No 1 TGI1A TGR1A input capture/compare-match Yes TGI1B TGR1B input capture/compare-match No TCI1V TCNT1 overflow No TCI1U TCNT1 underflow No 2 TGI2A TGR2A input capture/compare-match Yes TGI2B TGR2B input capture/compare-match No TCI2V TCNT2 overflow No TCI2U TCNT2 underflow No Low Note: * Indicates the initial status following reset. The ranking of channels can be altered using the interrupt controller. 10.5.2 DMAC Activation The TGRA register input capture/compare-match interrupt of any channel can be used as a source to activate the on-chip DMAC. For details, refer to section 9, Direct Memory Access Controller (DMAC). The MTU has three TGRA register input capture/compare-match interrupts, one for any channel, that can be used as DMAC activation sources. 10.5.3 A/D Converter Activation The TGRA register input capture/compare-match of any channel can be used to activate the on- chip A/D converter. If the TTGE bit of the TIER is already set to 1 when the TGFA flag in the TSR is set to 1 by a TGRA register input capture/compare-match of any of the channels, an A/D conversion start request is sent to the A/D converter. If the MTU conversion start trigger is selected at such a time on the A/D converter side when this happens, the A/D conversion starts. |
