IMP SW/POWER LIMIT
(Impedance/power limiter
detection)
IMP: 8 or 4 ohm impedance switch setting
PL: Power limiter detection value
The voltage value of pin No. 135 of IC520 is displayed,
using 5V/256 as standard.
When the power is turned on, the speaker impedance
switch setting is automatically detected, using the input
voltage value of pin No. 135 of IC520.
The output of ports No.60 and No. 61 are controlled by
using the input voltage value of pin No. 135 of IC520.
When higher than VthH, the port output is changed
from L to H.
When lower than VthH, the port output is changed from
H to L.
IMP SW/POWER LIMIT (インピーダンス/パワーリミッ
ターの検出)
IMP: インピーダンスSW検出の値
PL: パワーリミッター検出の値
IC520 135ピンの電圧値を5V/256を基準にして表示し
ます。
IC520 135ピンの入力電圧値により、ポートNo.60と61
の出力を制御します。
VthHを越えた場合、ポート出力をLからHにします。
VthLを下回った場合、ポート出力をHからLにします。

A/D of the key fails to function properly when the standard
value is deviated by
±
4%. In this case, check the constant
of partial pressure resistor, solder condition, etc. Refer to
table 2.
