厂商指令发下去了 我在厂商指令函数中读取的ep0buf数据没问题 我现在就是想看看ep0out中断是怎么回事 手册上说接受完ep0buf数据后就可以进入ep0out中断了 但我怎么也进不去 epie我也給赋值了0x02 手册原话:For EP0 OUT transfers, EZ-USB logic will NAK all OUT tokens to EP0 until the firmware has“armed” EP0 for OUT transfers by writing any value to the EP0BCL register. BUSY is automatically
set to 1 when the firmware writes to EP0BCL, and BUSY is automatically cleared to 0 after the
data has been correctly received and ACK’d. When BUSY transitions to zero, the EZ-USB also
generates an EP0OUT interrupt request. 您有这个ep0out中断的历程吗?2#dqyubsh
