Function Documentation

void hook_fgv	(	unsigned char	vector_number,
		unsigned short	addr
	)

Hook fifo/gpif interrupt vector.

vector_number is from the FGV_<foo> list. addr is the address of the interrupt service routine.

Parameters:

vector_number	vector_number is from the SV_<foo> list in the header file.
addr	is the address of the interrupt service routine.

Definition at line 103 of file isr.c.

void hook_sv	(	unsigned char	vector_number,
		unsigned short	addr
	)

Hook standard interrupt vector.

vector_number is from the SV_<foo> list. addr is the address of the interrupt service routine.

Parameters:

vector_number	vector_number is from the SV_<foo> list in the header file.
addr	is the address of the interrupt service routine.

Definition at line 49 of file isr.c.

void hook_uv	(	unsigned char	vector_number,
		unsigned short	addr
	)

Hook usb interrupt vector.

vector_number is from the UV_<foo> list. addr is the address of the interrupt service routine.

Parameters:

vector_number	vector_number is from the SV_<foo> list in the header file.
addr	is the address of the interrupt service routine.

Definition at line 76 of file isr.c.

void setup_autovectors

(

void

)

One time call to enable autovectoring for both USB and FIFO/GPIF.

This disables all USB and FIFO/GPIF interrupts and clears any pending interrupts too. It leaves the master USB and FIFO/GPIF interrupts enabled.
