Host n Frame Register [R]

• Host 1 Frame Register 0xC096

• Host 2 Frame Register 0xC0B6

Figure 29. Host n Frame Register

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
