24 * 5x RGMII Ethernet - 5x20 = 100 pins [[shakti/m_class/RGMII/]]
25 * 2x USB ULPI - 2x12 = 24 pins [[shakti/m_class/ULPI/]]
26 * SDRAM - 39 pins [[shakti/m_class/sdram/]]
28 * JTAG - 4 pins [[shakti/m_class/JTAG/]]
29 * 1.8v Core Power Vdd - 13 pins
30 * 1.8v Core Power Vss - 13 pins
31 * 3.3v IO Power Vdd - 10 pins
32 * 3.3v IO Power Vss - 10 pins
35 * SPI - 4 pins [[shakti/m_class/SPI/]]
42 * QSPI - Could share with SPI - 6 pins [[shakti/m_class/QSPI/]]
43 * SD/MMC - Could share with SPI - 4 pins
47 GPIO, EINT, Vdd, Vss, SDRAM, reset, PLL pin counts come from the LS180 pinmux definitions.
