Mmio Gpio Addressen Für Leds Und Batterieüberwachung - Siemens SIMATIC IPC127E Betriebsanleitung

10.4.3 MMIO GPIO Addressen für LEDs und Batterieüberwachung
COMMUINTY_BASE = Bus 0 Device 0x0d Function 0 Reg. 0x10
GPIO North Community PORT ID = 0xC5
GPIO North West Community PORT ID = 0xC4
GPIO_PADBAR = COMMUINTY_BASE + PORT ID << 16 + 0x500
GPO Reg = GPIO_PADBAR + GPIO_Offset Bit [0] (LEDs)
GPI Reg = GPIO_PADBAR + GPIO_Offset Bit [1] (Battery)
Example: Reg LED_USER1_RD_N_P1V8A = 0xD0C506A0
