Setting the peripheral enable switches

Switch Peripheral
S1-1 DAC
S1-2 ADC
S1-3 CAN 1
S1-4 CAN 2
S1-5 UART
S1-6 I2C
S1-7 USB 1 and 2
S1-7 IDE
ARM DUI 0188C
The peripheral enable switches on S1 enable the buffers and interface logic on the
Interface Tile. Disabling a peripheral allows the Versatile Logic Tile signals associated
with that peripheral to be used on the prototyping area.
Note
The camera interface does not have isolation logic. Remove the camera module from
the Interface Tile to isolate the camera signals from the tile signals.
Isolated peripheral signals
DAC_nCS
ADC_nCS
CAN1_RxD
CAN2_RxD
UART_TxD, UART_RxD, UART_nRTS,
UART_nDTR, UART_nCTS, UART_nDSR,
UART_nDCD, and UART_nRI
