AT91SAM7 hardware definitions — Details on obtaining hardware definitions for AT91

Device Definitions

The file <cyg/hal/plf_io.h> provides definitions related to AT91SAM7 subsystems. This file should not be included explicitly, but is included automatically whenever <cyg/hal/hal_io.h> is included. This file mainly includes base address definitions for the interrupt controller, power management controller, clock generator, memory controller, external bus interface, GPIO, USART, MCI, CAN, TWI (I²C®), Ethernet, timer counter, RTC, and SPI subsystems, depending on the exact model.
