20.7.18 Transfer Timing from Buffer Register
20.7.19 A/D Trigger Generation
• Transfer from the TRDGRD0, TRDGRC1, or TRDGRD1 register to the TRDGRB0, TRDGRA1, or
Compare match between registers TRD0 and TRDGRA0 and TRD1 underflow can be used as the conversion
start trigger of the A/D converter.
Use bits ADEG and ADTRG in the TRDFCR register and the TRDADCR register to make settings.
In addition, set bits ADCAP1 to ADCAP0 in the ADMOD register to 01b (A/D conversion starts by conversion
trigger from timer RD).
TRDGRB1 register.
When bits CMD1 to CMD0 in the TRDFCR register are set to 10b, the content is transferred when the TRD1
register underflows.
When bits CMD1 to CMD0 are set to 11b, the content is transferred at compare match between registers
TRD0 and TRDGRA0.
