Port A SOF/EOP Enable (Bit 0)
The Port A SOF/EOP Enable bit is only applicable in host mode.
In device mode this bit must be written as ‘0’. In host mode this
bit enables or disables SOFs or EOPs for Port A. Either SOFs or
EOPs are generated depending on the LOA bit in the USB n
Control register when Port A is active.
1: Enable SOFs or EOPs
0: Disable SOFs or EOPs
USB Host Only Registers
There are twelve sets of dedicated registers for USB host only operation. Each set consists of two identical registers (unless otherwise
noted), one for Host Port 1 and one for Host Port 2. These register sets are covered in this section and summarized in

Preamble Enable (Bit 7)
The Preamble Enable bit enables or disables the transmission of
a preamble packet before all low-speed packets. Set this bit only
when communicating with a low-speed device.
1: Enable Preamble packet
0: Disable Preamble packet
