Section 11 Multi-Function Timer Pulse Unit 2 (MTU2)
11.5.2 DMAC Activation
The DMAC can be activated by the TGRA input capture/compare match interrupt in each channel.
For details, see section 10, Direct Memory Access Controller (DMAC).
In the MTU2, a total of five TGRA input capture/compare match interrupts can be used as DMAC
activation sources, one each for channels 0 to 4.
11.5.3 A/D Converter Activation
The A/D converter can be activated by one of the following three methods in the MTU2. Table
11.56 shows the relationship between interrupt sources and A/D converter start request signals.
(1) A/D Converter Activation by TGRA Input Capture/Compare Match or at TCNT_4
Trough in Complementary PWM Mode
The A/D converter can be activated by the occurrence of a TGRA input capture/compare match in
each channel. In addition, if complementary PWM operation is performed while the TTGE2 bit in
TIER_4 is set to 1, the A/D converter can be activated at the trough of TCNT_4 count (TCNT_4 =
H'0000).
A/D converter start request signal TRGAN is issued to the A/D converter under either one of the
following conditions.
• When the TGFA flag in TSR is set to 1 by the occurrence of a TGRA input capture/compare
match on a particular channel while the TTGE bit in TIER is set to 1
• When the TCNT_4 count reaches the trough (TCNT_4 = H'0000) during complementary
PWM operation while the TTGE2 bit in TIER_4 is set to 1
When either condition is satisfied, if A/D converter start signal TRGAN from the MTU2 is
selected as the trigger in the A/D converter, A/D conversion will start.
(2) A/D Converter Activation by Compare Match between TCNT_0 and TGRE_0
The A/D converter can be activated by generating A/D converter start request signal TRG0N
when a compare match occurs between TCNT_0 and TGRE_0 in channel 0.
When the TGFE flag in TSR2_0 is set to 1 by the occurrence of a compare match between
TCNT_0 and TGRE_0 in channel 0 while the TTGE2 bit in TIER2_0 is set to 1, A/D converter
start request TGR0N is issued to the A/D converter. If A/D converter start signal TGR0N from the
MTU2 is selected as the trigger in the A/D converter, A/D conversion will start.
