Module RW

Constants

• CM_0
  No operation
• CM_1
  Count rising edges of primary sourceRising edges are counted only when SCTRL[IPS] = 0. Falling edges are counted when SCTRL[IPS] = 1. If the primary count source is IP bus clock divide by 1, only rising edges are counted regardless of the value of SCTRL[IPS].
• CM_2
  Count rising and falling edges of primary sourceIP bus clock divide by 1 cannot be used as a primary count source in edge count mode.
• CM_3
  Count rising edges of primary source while secondary input high active
• CM_4
  Quadrature count mode, uses primary and secondary sources
• CM_5
  Count rising edges of primary source; secondary source specifies directionRising edges are counted only when SCTRL[IPS] = 0. Falling edges are counted when SCTRL[IPS] = 1.
• CM_6
  Edge of secondary source triggers primary count until compare
• CM_7
  Cascaded counter mode (up/down)The primary count source must be set to one of the counter outputs.
