I
For normal mode of operation connect this Pin to Ground. Has an internal pulldown
resistor of 50 K ohm.
GPIO15
21
IO
This pin is available as a general-purpose input/output port. Also it is optionally
programmable to give out the external chip select signal meant for external SRAM.
Connect pullup resistor to supply if external SRAM used. It is also address line A19 when
1MB parallel flash is used.
JTAG_BS_ENn
22
I
JTAG Boundary Scan enabling pin. Has an internal pulldown resistor of 50 K ohm.
If this pin is left open or pulled down, Boundary Scan Mode is enabled.
If this pin is pulled high, Boundary Scan functionality is not available, and pins 34~37 are
available as GPIO 0~3
