Compare match between registers TRD0 and TRDGRA0 and TRD1 underflow can be used as the conversion
start trigger of the A/D converter. The trigger is selected by bits ADEG and ADTRG in the TRDFCR register.
Also, set the ADCAP bit in the ADCON0 register to 1 (starts by timer RD).
• Transfer from the TRDGRD0, TRDGRC1, or TRDGRD1 register to the TRDGRB0, TRDGRA1, or

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.
