PRPIF1 tw(PIF_DATA_INH) Pulse duration, PIF_DATA_IN high 2 + 0.475*(4*P)(1) ns
PRPIF2 tw(PIF_DATA_INL) Pulse duration, PIF_DATA_IN low 2 + 0.475*(4*P)(1) ns
(1) P = 1x (or TX) clock period in ns, defined by PRUn_ED_TX_DIV_FACTOR and PRUn_ED_TX_DIV_FACTOR_FRAC in the ICSSG_PRUn_ED_TX_CFG_REG register. PRUn represents the respective PRU0 or PRU1 instance.
