RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)

Figure 23.114 A/D Converter Start Request When 0 is Written to MTU4.TADCOBRA

Figure 23.115 A/D Converter Start Request When the Same Value as TCDR is Written to MTU4.TADCOBRA

A/D converter start

request (TRG4AN)

Complementary PWM mode

UT4AE = 1

DT4AE = 0

BF[1:0] = 10b (transfer at trough)

MTU4.TCNT

Write 0 to MTU4.TADCOBRA

An A/D converter start request is not issued during up-counting

immediately after buffer transfer (trough).

UT4AE, DT4AE, BF[1:0]: Bits in TADCR

Note 1. An A/D converter start request is issued when TCDR – 1

 MTU4.TADCOBRA/TADCOBRB  1

is written.

MTU4.TADCORA

MTU4.TADCOBRA

A/D converter start

request (TRG4AN)

Complementary PWM mode

UT4AE = 0

DT4AE = 1

BF[1:0] = 01b (transfer at crest)

Write the same value as TCDR to MTU4.TADCOBRA

An A/D converter start request is not issued during down-counting

immediately after buffer transfer (crest).
