(5) UF0 SNDSIE register (UF0SDS)
UF0SDS
Bit position
This register performs manipulation such as no handshake. It can directly manipulate the pins of SIE.
This register can be read or written in 8-bit units.
Be sure to clear bit 2 to “0”. If it is set to 1, the operation is not guaranteed.

CHAPTER 22 USB FUNCTION CONTROLLER (USBF)
This bit makes Endpoint0 issue a STALL handshake. Setting this bit to 1 if a request for
CPUDEC processing is not supported by the system results in a STALL handshake
response. If an unsupported wValue is sent by the SET_CONFIGURATION or
SET_INTERFACE request, the hardware sets this bit to 1. If a problem occurs in
Endpoint0 due to overrun of an automatically executed request, this bit is also set to 1.
However, the E0HALT bit of the UF0E0SL register is not set to 1.
This bit is cleared to 0 and the handshake response to the bus is other than STALL when
the next SETUP token is received. To set the SNDSTL bit to 1 by FW, do not write data
to the UF0E0W register. Depending on the timing of setting this bit, the STALL response
is not made in time, and it may be made to the next transfer after a NAK response has
been made.
Setting this bit is valid only while an FW-executed request is under execution when this
bit is set to 1. It is automatically cleared to 0 when the next SETUP token is received.
Remark The SNDSTL bit is valid only for an FW-executed request.
This bit outputs the Resume signal onto the USB bus. Writing this bit is invalid unless
the RMWK bit of the UF0DSTL register is set to 1.
While this bit is set to 1, the Resume signal continues to be generated. Clear this bit to 0
by FW after a specific time has elapsed. Because the signal is internally sampled at the
clock, the operation is guaranteed only while CLK is supplied. Care must be exercised
when CLK of the system is stopped.
