(4) A/D converter n mode register 2 (ADAnM2) (n = 0, 1)
Note In 4-buffer mode, the A/D conversion results are stored in the order of ADAnCR0 → ADAnCR1 →
Cautions 1. The external triggers of A/D converters 0 and 1 are respectively input from the
The ADAnM2 register is an 8-bit register that specifies the buffer mode and hardware trigger mode.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
ADAnCR2 → ADAnCR3 (in 4-buffer mode when using the operational amplifier for input-level
amplification: ADAnCR4 → ADAnCR5 → ADAnCR6 → ADAnCR7) regardless of the selected analog
input pin.
Setting of the 4-buffer mode is prohibited in the continuous scan mode and one-shot scan mode.
2. The timer trigger of A/D converter n is the A/D conversion start trigger signal (TQTADTa0,

therefore, be sure to set the PMC0.PMC04 and PMC0.PMC05 bits to 1.
TQTADTa1) of the timer (motor control function). The TQTADTa0 and TQTADTa1 signals
are connected to the TTRG0a and TTRG1a signals of A/D converter n (see Figure 12-3)
(V850E/IA3: a = 0, V850E/IA4: a = 0, 1).
• Timer trigger of A/D converter 0
• Timer trigger of A/D converter 1
The TQTADTa0 and TQTADTa1 signals are set by using the TQaAT00 to TQaAT03 bits of
TMQa option register 2 (TQaOPT2) and the TQaAT10 to TQaAT13 bits of TMQa option
register 3 (TQaOPT3). The trigger sources of the motor control function that can be
selected as an A/D conversion start trigger (timer trigger) are the INTTPaCC0, INTTPaCC1,
INTTQaCC0, and INTTQaOV signals (two or more signals can be selected).
