Endpoint Type
• BK_NUMBER: Number of Banks
Set this field according to the endpoint’s number of banks (see
Number of Banks
• NB_TRANS: Number Of Transaction per Microframe
The Number of transactions per microframe is set by software.
Note:
• EPT_MAPD: Endpoint Mapped
0 = the user should reprogram the register with correct values.
1 = set by hardware when the endpoint size (EPT_SIZE) and the number of banks (BK_NUMBER) are correct regarding:
