d. <com[3:0]>
Sets the command to be issued for the endpoint selected in ep[3:0].
0x0: Reserved
0x1: Setup_Fin
0x2: Set_DATA0
0x3: EP_Reset
0x4: EP_Stall
0x5: EP_Invalid
Not to be specified.
(Should be issued only for EP0.)
This is a command for setting the end of DATA-Stage in Control
transfers. As UDC2 continues to send back “NAK” to the
STATUS-Stage until this command is issued, the command should be
issued when the DATA-Stage finishes or INT_STATUS_NAK was
received.
Note: “Setup_Fin” command after reading all received data during data stage of
(Can be issued to EPs except EP0. Should not be issued to EP0.)
A command for clearing toggling of endpoints. While toggling is
automatically updated by UDC2 in normal transfers, this command
should be issued if it needs to be cleared by software.
(Can be issued to any EP.)
A command for clearing the data and status of endpoints. Issue this
command when you want to reset an endpoint in such cases as setting
endpoints of Set_Configuration and Set_Interface or resetting the
endpoint by Clear_Feature. This command will reset the following 5
points:
UDC2 makes toggling control by hardware for every transfer. If this
command is issued when a transfer of endpoints is in progress,
toggling of the relevant endpoint will also be cleared which may cause
the synchronization with the host be lost. As in the case of receiving
requests as mentioned above, the command should be issued when it is
possible to make synchronization with the host.
(Can be issued to any EP.)
A command for setting the status of endpoints to “Stall”. Issue this
command when you want to set the status of an endpoint to “Stall” in
such cases as stalling an endpoint by Set_Feature. When this
command is issued, “STALL” will be always sent back for the endpoint
set. However, the Stall status of EP0 will be cleared when the
Setup-Token is received.
This command should not be issued for endpoints where Isochronous
transfers are used, since transfers are made without Handshake in
Isochronous transfers. Even if this command is issued for endpoints
where Isochronous transfers are set (by t_type (bits[3:2]) of
EPx_Status register), “STALL” will not be sent back.
(Can be issued to EPs except EP0. Should not be issued to EP0.)
A command for setting the status of endpoints to “Invalid”. Please
issue this command when disabling endpoints that will not be used
when using Set_Config or Set_Interface to set endpoints. When this
command is issued, the endpoints set will make no response. This
command should not be issued while transfers of each endpoint are in
progress.
1. Clear the bits 13-12 (toggle) of EP0/EPx_Status register to DATA0
