PH1-sLD3: UART3 is unavailable PH1-LD4, PH1-sLD8: only IRQ 29 is supported PH1-Pro4: both IRQ 29 and 177 are supported PH1-Pro5, ProXstream2, PH1-LD6b: only IRQ 177 is supported This SoC can choose either IRQ 29 or IRQ 177, but the former is shared with another hardware (low speed serial0). The latter is dedicated for this hardware and more recommended.
