|
|
*
|
|
* TOP5200 differences from IceCube:
|
|
* 1 FLASH Bank for one Chip only, up to 64 MB in 16 MB Banks
|
|
* bank switch controlled by TIMER_6(LSB) and TIMER_7(MSB) Pins
|
|
* 1 SDRAM/DDRAM Bank up to 256 MB
|
|
* local VPD I2C Bus is software driven and uses
|
|
* GPIO_WKUP_6 for SDA, GPIO_WKUP_7 for SCL
|
|
* FLASH is re-located at 0xff000000
|
|
* Internal regs are at 0xf0000000
|
|
* Reset jumps to 0x00000100
