Functions
static void	chip_isr (void)
static void	init_chip_pins (void)
	Initialize reset, chip enable and wake pin. More...
sint8	nm_bsp_deinit (void)
	De-iInitialize BSP. More...
sint8	nm_bsp_init (void)
	Initialize BSP. More...
void	nm_bsp_interrupt_ctrl (uint8 u8Enable)
	Enable/Disable interrupts from the WINC. More...
void	nm_bsp_register_isr (tpfNmBspIsr pfIsr)
	Register the host interface interrupt service routine. More...
void	nm_bsp_reset (void)
	Reset NMC1500 SoC by setting CHIP_EN and RESET_N signals low, CHIP_EN high then RESET_N high. More...
void	nm_bsp_sleep (uint32 u32TimeMsec)
	Used to put the host to sleep for the specified duration (in milliseconds). Forcing the host to sleep for extended period may lead to host not being able to respond to WINC board events. It is important to be considerate while choosing the sleep period. More...
