Endpoint Control Registers  
Endpoint n Control Register [Address a = (EP# * 10h), b = (EP# * 10h)+8]. Each endpoint set has a Control register defined as  
follows:  
Table 22. Endpoint Control Register [Address EP0a/b:00h/08h, EP1a/b:10h/18h, EP2a/b:20h/28h, EP3a/b:30h/38h]

Sequence bit. '0' if DATA0, '1' if DATA1.  
When set to ‘1’, sends Stall in response to next request on this endpoint.  
When set to '1', allows Isochronous mode for this endpoint.  
'0' if next data set is ‘A’, '1' if next data set is 'B'.  
Next Data Set  
Direction  
Enable  
When Direction = '1', transmit to Host (IN). When Direction = '0', receive from Host (OUT).  
When Enable = '1', allows transfers for this endpoint. When set to ‘0’, USB transactions are  
ignored. If Enable = '1' and Arm = '0', the endpoint returns NAKs to USB transmissions.  
0
Arm  
Allows enabled transfers when set =’1’. Clears to '0' when transfer is complete.  
Endpoint Base Address [Address a = (EP# * 10h)+1, b = (EP# * 10h)+9]]. Pointer to memory buffer location for USB reads and  
writes.  
Table 23. Endpoint Base Address Reg [Address; EP0a/b:01h/09h, EP1a/b:11h/19h, EP2a/b:21h/29h, EP3a/b:31h/39h]

Endpoint Base Length [Address a = (EP# * 10h)+2, b = (EP# * 10h)+A]. The Endpoint Base Length is the maximum packet size  
for IN/OUT transfers with the host. Essentially, this designates the largest packet size that is received by the SL811HS with an OUT  
transfer, or it designates the size of the data packet sent to the host for IN transfers.  
Table 24. Endpoint Base Length Reg [Address EP0a/b:02h/0Ah, EP1a/b:12h/1Ah, EP2a/b:22h/2Ah, EP3a/b:32h/3Ah]
