18.3.5
Endpoint Direction Register 0 (EPDIR0)
EPDIR0 controls the direction of data transfer for endpoints other than endpoint 0 of the USB
function core. In this LSI, EP1, EP3 and EP4 must be specified as host input transfers, EP5 as a
host output transfer, and EP2 as either a host input transfer or host output transfer.
EPDIR0 is initialized to H'3C by a system reset or function software reset (see section 18.3.16,
USB Control Registers 0 and 1 (USBCR0, USBCR1)).
