Notes:
1.
All +3.3VDC must use a 0.1-
µF bypass capacitor and these capacitors must be placed near the SL11RIDE chip.
2.
48-MHz Crystal or oscillator has to use a capacitor 0.1
µF to filter output signals. It must be placed at least ¾” from 3.3V, 5.0V or a USB connector
3.
All pins not shown (NC pins and reserved pins) should not be connected or used for other purposes.
4.
This signal requires a 1- to 5-k
Ω pull-up.
5.
GPIO26: This signal can be used for device low power mode. It will turn off or disable external powers to the peripheral in suspend mode. Once USB power is
resumed, external power can be enabled again
6.
GPIO25 can be used as INTRQ/HW_RESET/RB and GPIO24 can be used as DASP/WP signals. These signals are used for CF and Smart Media to exchange
media cards or insert/remove media while power is still supplied to the board.
