When using Endpoint 1 and Endpoint 2 with DMA (Endpoint I/F) and using only Endpoint3
via PVCI-I/F
Interrupt responses to EP3 will be identical whether bit 3 of INT_EP register or bit 6 of INT
register is used. It may be better to use INT register alone in terms of efficiency since
checking only one register will do. Use INT register for interrupt responses.
When you have more than one EPx to be controlled by PVCI-I/F in addition to EP0
by PVCI-I/F, while EP1 uses DMA.
mask it. When making interrupt responses for more than one EPs, be sure to use INT_EP
register. Ignore i_ep of INT register and always enable m_ep as 0.
need to check INT and INT_EP registers to determine the source. When clearing the source,
use each source bit of INT_EP interrupt to clear it.
An example of using i_ep/INT_EP/INT_EP_MASK is provided below for Endpoints 1 to 3.
After initialization, set 1 to the bits 1 and 2 of INT_EP_MASK register to mask them.
The following descriptions are based on the assumption that EP2 and EP3 are controlled
After initialization, set 1 to INT_EP_MASK register of the EP to be used with DMA to
Do not clear the source using i_ep of INT register. After the interrupt has occurred, you
