LS IA IG 1. Unless noted otherwise, all parameters use a GRP load of 4 GLBs, 20 PTXOR path, ORP and Y0 clock.
S 2. Refer to Timing Model in this data sheet for further details.
p C 3. Standard 16-Bit loadable counter using GRP feedback.
E 4. fmax (Toggle) may be less than 1/(twh + twl). This is to allow for a clock duty cycle of other than 50%.
