User manual
9.5.3 USB Endpoint Index register (USBEpIn - 0xFFE0 C248)
9.5.4 USB MaxPacketSize register (USBMaxPSize - 0xFFE0 C24C)
}
The device will not respond to any transactions to unrealized endpoints. The SIE
Configure Device command will only cause realized and enabled endpoints to respond to
transactions. For details see
Each endpoint has a register carrying the MaxPacketSize value for that endpoint. This is
in fact a register array. Hence before writing, this register is addressed through the
USBEpIn register.
The USBEpIn register will hold the physical endpoint number. Writing to USBMaxPSize
will set the array element pointed to by USBEpIn. USBEpIn is a write only register.
Table 319. USB Endpoint Index register (USBEpIn - address 0xFFE0 C248) bit description
On reset, the control endpoint is assigned the maximum packet size of 8 bytes. Other
endpoints are assigned 0. Modifying USBMaxPSize will cause the endpoint buffer
addresses within the EP_RAM to be recalculated. This is a multi-cycle process. At the
end, the EP_RLZED bit will be set in USBDevIntSt
