dieptxf13
This register holds the size and memory start address of IN endpoint TxFIFOs implemented in Device mode. Each FIFO holds the data for one IN endpoint. This register is repeated for each instantiated IN endpoint FIFO. For IN endpoint FIFO 0 use GNPTXFSIZ register for programming the size and memory start address.

Important: To prevent indeterminate
system behavior, reserved areas of memory must not be accessed by software or
hardware. Any area of the memory map that is not explicitly defined as a register
space or accessible memory is considered reserved.
