Bit 7:
Stall
When this bit is set the SIE will stall an OUT packet if the Mode Bits are set to ACK-OUT, and the SIE will stall an IN packet if
the mode bits are set to ACK-IN. This bit must be clear for all other modes
Bit 6:
Reserved
Bit 5:
NAK Int Enable
This bit when set causes an endpoint interrupt to be generated even when a transfer completes with a NAK. Unlike enCoRe,
enCoRe II family members do not generate an endpoint interrupt under these conditions unless this bit is set
0 = Disable interrupt on NAK’d transactions
1 = Enable interrupt on NAK’d transaction
Bit 4:
ACK’d Transaction
The ACK’d transaction bit is set whenever the SIE engages in a transaction to the register’s endpoint that completes with an
ACK packet.
This bit is cleared by any writes to the register
0 = The transaction does not complete with an ACK
1 = The transaction completes with an ACK
Bit [3:0]:
Mode [3:0]
The endpoint modes determine how the SIE responds to USB traffic that the host sends to the endpoint. The mode controls how the
USB SIE responds to traffic and how the USB SIE will change the mode of that endpoint as a result of host packets to the endpoint.
Note:
When the SIE writes to the EP1MODE or the EP2MODE register it blocks firmware writes to the EP2MODE or the EP1MODE
registers respectively (if both writes occur in the same clock cycle). This is because the design employs only one common ‘update’
signal for both EP1MODE and EP2MODE registers. Thus, when SIE writes to say EP1MODE register, the update signal is set and
this prevents firmware writes to EP2MODE register. SIE writes to the endpoint mode registers have higher priority than firmware
writes. This mode register write block situation can put the endpoints in incorrect modes. Firmware must read the EP1/2MODE regis-
ters immediately following a firmware write and rewrite if the value read is incorrect.
