Issues

• AM243x: IEP runs at 0.8 counts per PRU cycle on LP-AM243 (200 MHz), simulator defaults iep_clock_mhz to the PRU clock

• IEP shadow compare mode (CMP_CFG SHADOW_EN) and PWM_EFC_EN status auto-clear are not modelled

• AM243x: ICSSG PWM module (PWM0..3, TRM 6.4.10) is not modelled - IEP compares drive no PWM pins, no trip zone

• AM243x: a PRU_CTRL CYCLE register read costs 6 cycles on silicon, 3 in the simulator

• AM243x MSRAM: an LBBO that straddles a 64 B boundary costs ~13 extra cycles (simulator has no line term)
