PRODUCTION DATA.
The TLC694x device uses the rising edge or both edges of GCLK. The selection is made by setting the GCLK_EDGE bit in the function control register. By default, the TLC6946 device uses the GCLK rising edge, and the maximum input GCLK frequency is 33 MHz. By setting GCLK_EDGE = 1, the TLC694x device operates at both GCLK edges (rising and falling), and the maximum internal GCLK frequency is 50 MHz with external 25MHz input.
