7.5.2.11 EP {r}(r=a,b,c) FIFO remain Counter (EPrFIFOremain) R
Shows the number of bytes of remaining data in FIFO of the endpoint.
USBIndex : 01h to 03h
Address Register Name
1Dh EPrFIFOremain
7.5.2.12 EPr FIFO for CPU (EPrFIFOforCPU) R/W
This register allows access to FIFO of the endpoint from the CPU.
When the EnFiFOwr bit of the EP0FIFOCtrl register is set, writing is enabled, when the EnFIFOrd bit is set,
reading is enabled.
It should be noted that reading or writing causes changes in the number of data in FIFO, as it is similar to access
from the USB.
