41 Data In Valid to CLKOUT rise (setup)
42 CLKOUT Rise to Data In Invalid (hold)
43 CLKOUT Rise to Data Out Valid (WSC>0)
44 CLKOUT Rise to Data Out Invalid (Output Hold) (WSC>0)
45 CLKOUT Rise to Data Out High Impedance (WSC>0)
46 CLKOUT Fall to Data Out Valid (WSC=0)
47 CLKOUT Rise to Data Out Invalid (Output Hold) (WSC=0)
48 CLKOUT Rise to Data Out High Impedance (WSC=0)
NOTES:
1. Output timing is measured at the pin. The specifications assume a capacitive load of 50 pF.
2. EB outputs are asserted for reads if the EBC bit in the corresponding CS control register is cleared
