Notes
1. All input, I/O (in input mode), output (in 3-state mode) and open drain output pins are 5.0 V tolerant.
2. In accordance with the "IEEE 1149.1" standard.
3. Special functionality of pin TRST:
a) For board designs without boundary scan implementation, pin TRST must be connected to ground.
b) Pin TRST provides easy initialization of the internal BST circuit. By applying a LOW it can be used to force the
internal Test Access Port (TAP) controller to the Test-Logic-Reset state (normal operation) at once.
The 208 pins are divided in following groups:
Video input port (11 pins):
8 data pins
3 control pins.
Data output port (23 pins):
16 data pins
7 control pins.
GPIO port (15 pins):
12 data pins
3 control pins.
DRAM (77 pins):
64 data pins
9 address pins
4 control pins.
