18.3.2
Endpoint Size Register 1 (EPSZR1)
EPSZR1 specifies the sizes of the FIFO (number of bytes) used in USB function core endpoints 1
and 2.
To use both endpoints 1 and 2 in this LSI, the size of FIFOs used for endpoints 1 and 2 must be
specified as 16 bytes. To use only endpoint 1 in this LSI, the size of FIFO used for endpoint 1
must be specified as 16 bytes or 32 bytes. If the size of FIFO used for endpoint 1 is specified as 32
bytes, the FIFO for endpoint 2 must be specified as 0 bytes.
EPSZR1 is initialized to H'44 by a system reset or function software reset (see section 18.3.16,
USB Control Registers 0 and 1 (USBCR0, USBCR1)).
