NXP JN516X (TWELITE) をプログラミングする（TIMER)

Timerには５つの機能があり機能毎に利用するメソッドが微妙に異なっている。機能毎にクラス分けすべきかもと思ったりもしたがなんとなくSDKをそのままラップしただけのライブラリに落ち着いてしまった。

但し、vAHI_TimerFineGrainDIOControl()については各タイマーを一括設定する仕様となっていて非常に使いずらいため個別設定ができるような仕様に変更している。

【機能毎の主メソッド】

[Timer]
begin()
startSingleShot()
startRepeat()

[PWM]
begin()
startSingleShot()
startRepeat()

[Counter]
clockSelect()
begin()
startSingleShot()
startRepeat()
readCount()

[Capture]
begin()
startSingleShot()
startRepeat()
readCapture()
peekCapture()

[Delta-Sigma]
startDeltaSigma()
