CCLKn and CIOn (n=1 to 5) slew rate control
Three registers SLEW_CTRL_1, SLEW_CTRL_2 and SLEW_CTRL_3 control the slew rate of
the CIOn and CCLKn signals. Each signal has 2 control bits.
An automatic mode is proposed. The VCARDn[1:0] value is used to automatically adjust the
slew rate.
For specific cases, like long wires between AT83C26 and smart card connector for example, the
user can forced the slew rate.
The rising edge and the falling edge are modified with the slew rate control for CCLKn.
Only the rising edge is modified on CIOn with the slew rate control.
See Table 63. to Table 68. in Electrical Characteristics.
