CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
The effects of internal clock jitter are included at test. There is no need to adjust timing numbers for internal clock jitter or SSCLK duty cycle.
P = 1/CPU clock frequency in ns. For example, when running parts at 150 MHz, use P = 6.67 ns.
*This parameter is not production tested.
