I know

- Peripheral Clock: 24Mhz
- CPU Block: 144Mhz

Please let me know the correct value of EXCPGCR ? Is 0x28 correct initialize value of USB clock?
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.
