Section 18 Universal Serial Bus Interface (USB)
18.3.19 Endpoint 4 Packet Size Register (EP4PKTSZR)
EP4PKTSZR specifies the MaxPacketSize for endpoint 4. In this LSI, only 64 bytes can be
specified as MaxPacketSize. Endpoint 4 receives transmit data from the RFU. The packet size of
endpoint 4 is controlled by the USB module and transmit data is transferred from the RFU until
the number of transmit data bytes reaches the value specified in EP4PKTSZR.
EP4PKTSZR is initialized to H'40 by a system reset or function software reset (see section
18.3.16, USB Control Registers 0 and 1 (USBCR0, USBCR1)).
