OHCI memory mapped registers structure. More...

#include <ohci_regs.h>

Data Fields
volatile uint32_t	bulk_current
	Currently executed bulk endpoint.
volatile uint32_t	bulk_head
	The first bulk endpoint.
volatile uint32_t	command_status
volatile uint32_t	control
volatile uint32_t	control_current
	Currently executed control endpoint.
volatile uint32_t	control_head
	The first control endpoint.
const volatile uint32_t	done_head
	Done TD list, this value is periodically written to HCCA.
volatile uint32_t	fm_interval
	Frame time and max packet size for all transfers.
const volatile uint32_t	fm_number
	Frame number.
const volatile uint32_t	fm_remaining
	Bit times remaining in current frame.
volatile uint32_t	hcca
	HCCA pointer (see hw_struct hcca.h).
volatile uint32_t	interrupt_disable
volatile uint32_t	interrupt_enable
volatile uint32_t	interrupt_status
	Interupt enable/disable/status, reads give the same value, writing causes enable/disable, status is write-clean (writing 1 clears the bit.
volatile uint32_t	ls_threshold
	Threshold for starting LS transaction.
const volatile uint32_t	periodic_current
	Currently executed periodic endpoint.
volatile uint32_t	periodic_start
	Remaining bit time in frame to start periodic transfers.
const volatile uint32_t	revision
volatile uint32_t	rh_desc_a
	The first root hub control register.
volatile uint32_t	rh_desc_b
	The other root hub control register.
volatile uint32_t	rh_port_status []
	Root hub per port status.
volatile uint32_t	rh_status
	Root hub status register.
