Initialization sequence

01. Apply clock to 10359

02. fpcf -i2cw16 807 1 - switch i2c bus to EEPROM & CY22393

03. fpcf -X 4 96 - switch internal 96MHz on the 10359

04. fpcf -i2cw16 808 1 - switch from the 10353's clock to the 10359's generated clock

05. fpcf -i2cw16 801 3 - reset system clock DCM

06. fpcf -i2cw16 802 3 - reset SDRAM clock DCM

07. fpcf -i2cw16 803 3 - reset J2 DCM

08. fpcf -i2cw16 804 3 - reset J3 DCM

09. fpcf -i2cw16 805 3 - reset J4 DCM

10. fpcf -i2cw16 807 0 - switch i2c bus back to sensors

Write registers

All the registers are 16 bit wide

DDR SDRAM test write registers

Phase adjust register - 0x802
