Register Description

The Host n Frame register maintains the next frame number to be transmitted (current frame number + 1). This value is updated after each SOF transmission. This register resets to 0x0000 after each CPU write to the Host n SOF/EOP Count register (Host 1: 0xC092, Host 2: 0xC0B2).

Frame (Bits [10:0])

The Frame field contains the next frame number to be trans- mitted.

Reserved

All reserved bits must be written as ‘0’.

USB Device Only Registers

There are ten sets of USB Device Only registers. All sets consist of at least two registers, one for Device Port 1 and one for Device Port 2. In addition, each Device port has eight possible endpoints. This gives each endpoint register set eight registers for each Device Port for a total of 16 registers per set. The USB Device Only registers are covered in this section and summarized in Table 27.
