<LCDEN SignalPulseDuration> if ChipSelect = LCDEN (default value is 0)
The <Lcd LcdenSignalPulseDuration> value is between 0 and 31.
The resulting time is :
For P32X3 product: ( X + 1.5 ) * 38.5 ns ;
For P32X6 product : ( 1 + 2 * ( X + 1 ) ) * 19 ns
(Warning, for this product, the 0 value in considered as 32).
This is the time during which the LCD_EN signal is valid (T2 on the figure above).
<LCDEN PolarityControl> if ChipSelect = LCDEN (default value is 0)
0 : LOW (LCD_EN signal is valid on low state)
1 : HIGH (LCD_EN signal is valid on high state)
<GPIO NbWaitState> if ChipSelect = GPIO (default value is 0)
This is the time during which the data is valid on the bus.
0 : 62 ns
1 : 100 ns
2 : 138 ns
3 : 176 ns
Notes :
z If one or two IOs are needed by a bus, they are not available any more for the +WIOR , +WIOW,
+WIOM commands. When the corresponding bus is closed, these commands resume the control of
the IOs.
z A bus may not be available for an open operation if an Open-AT embedded application has opened
it before with the same parameters. In this case, the +WBM command will return +CME ERROR:
