SAM9 hardware definitions — Details on obtaining hardware definitions for SAM9
<cyg/hal/sam9.h> can be included from
application and eCos package sources to provide definitions related to SAM9
subsystems. These include register definitions for the interrupt controller,
power management controller, clock generator, memory controller, external bus
interface, GPIO, USART, MCI, TWI (I²C®), Ethernet,
timer counter, RTTC, and SPI subsystems.
Initialization helper macros
definitions of helper macros which may be used by SAM9 platform
HALs in order to initialise common SAM9 subsystems without
excessive duplication between the platform HALs. Typically this file
will be included by the
hal_platform_setup.h header in the platform HAL,
in turn included from the architectural HAL file
This file is solely intended to be used by platform HALs. At the same time, it is only present to assist initialization, and platform HALs are not obliged to use it if their startup requirements vary.
