Detailed Description

Software driver functions for input capture.

PA12 is digital wave input, index 33 in IOMUX PINCM table.

• G0 in power domain PD0, so
  • for 32MHz bus clock, SYSCLK clock is 32MHz
  • for 40MHz bus clock, SYSCLK clock is ULPCLK 20MHz
  • for 80MHz bus clock, SYSCLK clock is ULPCLK 40MHz
