1. FEI_CFG bits 8 and 9 must be programmed according to the required NRSS configuration.
2. The NRSS_IN and NRSS_OUT pins are swapped around on the STi5519 compared to the STi5508.
3. Inverted. ATTENTI0N! the PIO is also inverted.
4. The PIO must be configured in open drain
5. Tie low whenever JTAG is not used
6. BOOT_FROM_ROM is active during reset.
