Drive Register
The Drive Register configures the pin driver as Open Drain, or in the case of ECSPLD
outputs, sets the pin to operate in high slew rate. An external pull-up resistor is not required
when the pin is in the slew rate mode.
For Ports A and B the register sets different functions for the lower and higher nibbles. The
four upper bits set the corresponding bits the as CMOS (“0”) or Open Drain (“1”) driver. The
four lower bits are used for slew rate control. The slew rate is a measurement of the rise
and fall times of the output. A higher slew rate means a faster output response while a
lower slew rate is a slower, lower slope, response. The pin operates in high slew rate when
the corresponding bit in the Drive Register is set to “1”.
Table 20 shows the Drive Registers of Port A, B, C and D and which pin has the Open Drain
or Slew Rate configuration.
