Reset
Proper external reset is not required. The EM2000 has a reliable power-on reset
circuit with brown-out detection. Optionally, you can connect a reset button or
some other reset-generating circuit to the RST pin of the EM2000. This will allow
you to generate external resets. The RST line has active LOW polarity. If you are
not using the RST pin you can leave it unconnected.
PLL control
The EM2000 can run at three clock frequencies (speeds):
·
Full speed: 120MHz (default post-reset speed)
·
Medium speed: 43Mhz
·
Low speed: 16MHz
The clock speed can be changed programmatically, via the system (sys.) object.
For more information see TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual.
Mode selection
The function of the MD line is described in Setup Button (MD line).
