Programmable I/O Drive
Programmable Schmitt Trigger
The additional programmable delays for each supporting range from 0 to
PVT). The delay can differ between I/Os supporting this feature. Delay can be modified per pro-
gramming for each I/O. The minimal additional delay that can be programmed on a PAD
supporting this feature is 1/16 of the maximum programmable delay.
Only PADs PA[20:15], PA[13:11] and PA[4:2] can be configured.
When programming 0x0 in fields, no delay is added (reset value) and the propagation delay of
the pad buffers is the inherent delay of the pad buffer. When programming 0xF in fields, the
propagation delay of the corresponding pad is maximal.
Figure 23-9. Programmable I/O Delays
It is possible to configure the I/O drive for pads PA[20:15], PA[13:11] and PA[4:2]. For any
details, refer to the product electrical characteristics.
It is possible to configure each input for the Schmitt Trigger. By default the Schmitt trigger is
active. Disabling the Schmitt Trigger is requested when using the QTouch
PIO
