Sum square amplitude error

Integral value of sum square of monitor

output amplitude voltage (sin, cos) with an

interval within the excitation period

High side

0.8 × (RVCC±5%) [Vp-p]

Low side

0.2 × (RVCC±5%) [Vp-p]

Note 1.

Determined as an error, when both of SINMNT and COSMNT become under threshold.

Note 2.

Determined as an error, when DC level changed over threshold.

Note 3.

Determined as over, when control declination becomes over high side threshold, or under low side threshold.

Note 4.

Determined as an error, when control declination recognition rate becomes over 50% as average of period set by the EDPS

[1:0] bits in the RDC3AnDIAG1 register (default is about 7.4 ms). It might not be detected, when the error continuous period is

shorter than detect period.

Note 5.

Dependent on the excitation frequency and amplitude error excitation period count settings.
