25.5.11 Shadow Load and Lockout Control

In capture mode, this logic inhibits (locks out) any shadow loading of CAP1 or CAP2 from APRD and ACMP registers, respectively.

In APWM mode, shadow loading is active and two choices are permitted:

  • Immediate - APRD or ACMP are transferred to CAP1 or CAP2 immediately upon writing a new value.
  • On period equal, CTR[31:0] = PRD[31:0].
