USB function/Endpoint 2 error
interrupt bit
Not used
0 : No interrupt request issued
1 : Interrupt request issued
This bit is set to “1” when the buffer 0 is ready state
(enabled to be read/written) on USB function/Endpoint 2.
“0” can be set by software, but “1” cannot be set.
0 : No interrupt request issued
1 : Interrupt request issued
In single buffer mode this bit is invalid.
This bit is set to “1” when the buffer 1 is ready state
(enabled to be read/written) on USB function/Endpoint 2
in double buffer mode.
“0” can be set by software, but “1” cannot be set.
0 : No interrupt request issued
1 : Interrupt request issued
This bit is set to “1” when STALL response occurs on
USB function/Endpoint 2.
“0” can be set by software, but “1” cannot be set.
Write “0” when writing.
“0” is read when reading.
