Table 17.2-8 Bits of the CONT1 Register (2 / 2)
Bit name Polarity
AUTOBFOK ActiveHigh
IODIS ActiveHigh
Reserved ActiveHigh
Only '1' is valid for writing to the CFGEN bit.
STALL0, STALL1, STALL2, and STALL3 have a transfer request in Endpoint that set STALL, and
it is reset when STALL is transmitted.
Even though STALL0 is set, the macro responds correctly if the setup is received. In this case,
STALL0 is reset when the ACK response is performed for the setup.
If 1 is set when the received byte count of OUT side in ENDPOINT is 0, USB
transfer of OUT side in ENDPOINT0 is automatically enabled. At that time,
ST1.ACKO interrupt cause is not asserted. (Set CONT3.BFOKO
0
automatically.)
If this bit set to '1', the SUSPEND signal (macro output signal) is asserted.
When this bit is set or this device is in the suspend state, the SUSPEND
signal is asserted.
Write '0' to this bit.
