CLKRP = CLKXP = FSRP = FSXP = 0 in the pin control register (PCR). If polarity of any of the signals is inverted, then the timing references
of that signal are also inverted.
Minimum delay times also represent minimum output hold times.
§
P = 1/CPU clock frequency in ns. For example, when running parts at 167 MHz, use P = 6 ns.
C =
H or L
S =
sample rate generator input clock = P if CLKSM = 1 (P = 1/CPU clock frequency)
=
sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)
H =
CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
L =
CLKX low pulse width
= (CLKGDV/2) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
*This parameter is not tested.
