I think that 0x21 is correct value of EXCPGCR for your board. 0x21: 00101000 -> 00 100 001 -> * 100: Using Internal Clock * 001: Dividing Ratio Selection is 1/2 (96MHz / 2 = 48MHz) >> And I used my board, I set 0x1500 in PKCR. > I don't understand PKCR - Port control register so I don't know correct > initialize value of this register. > > 0x1500 = 0001 0101 0000 0000 > -> PK6 is port output > -> PK5 is port output > -> PK4 is port output > I don't know this value could be set for my board - TEngine/SH7727. Oh, I am very sorry. This is PECR. This setting enable USB1_pwr_en and USB2_pwr_en pin.
