upon the specific application, prior to be applied to the smart
card driver. On the other hand, the positive and negative
going slopes of the output clock (CRD_CLK) can be
programmed to optimize the operation of the chip

(Table 10). The slope of the output clock can be
programmed on the fly, independently of either the
CRD_VCC voltage or the operating frequency, but care
must be observed as the CRD_RST will reflect the logic
state present at MOSI/b4 register.
Note: Waveforms recorded without external compensation
