Each bit is asserted when the corresponding error occurs and is deasserted when SOP is received.
This register is used to report the error information. This register is useful for the tests during development, or for
preparing the error frequency measurement report. This register is not particularly required for the specification of
commercial a product.

This register reports the statuses of the EP0RXFIFO and the FIFO for EP1. Normally, there is no need to read this
register because it is sufficient to read the packet ready status before reading out or writing in a FIFO.
Receive FIFO0 Full:
This bit becomes “1” when 8-bytes of data are stored in the EP0RXFIFO. This bit is
not set to “1” when a packet less than 8 bytes long (a short packet) is stored in.
Receive FIFO0 Empty: This bit will be “1” when the EP0RXFIFO0 is empty.
FIFO1 Full:
This bit becomes “1” when 64 bytes of data is stored in the FIFO for EP1. This is true
during both transmission and reception. This bit does not become “1” in the case of a
short packet. The FIFO for EP1 has a two-layer structure and can store up to 128
bytes of data. This bit indicates the status of the FIFO in which data being written at
that time. In other words, this bit indicates the status of the FIFO into which the host
computer is writing data when EP1 is receiving data, and of the FIFO into which the
local MCU is writing data when EP1 is transmitting data.
FIFO1 Empty:
This bit becomes “1” when the FIFO for EP1 is empty. This is true during both
transmission and reception. The FIFO for EP1 has a two-layer structure and can store
up to 128 bytes of data. This bit indicates the status of the FIFO which is being read
out at that time.
