Description
reserved; write logic 0
Port 1 Initialization 2: Write logic 1 at the ISP1760 initialization. It will
clear both this bit and bit 7. Affects only port 1.
reserved; write logic 0
Port 1 Initialization 1: Must be reset to logic 0 at power-up initialization
for correct operation of port 1. Correct Host Controller functionality is not
ensured if set to logic 1 (affects only port 1). To clear this bit, logic 1 must
be written to bit 23 during the ISP1760 initialization.
This is not required for the normal functionality of port 2 and port 3.
reserved
Port 1 Power: Set these bits to 11b. These bits must be set to enable
port 1 power.
