During and after reset, the internal clock is selected as the CKI input pin and the CKO output pin is selected as the internal clock.
This pin his internal pull-up circuitry.
§
3-states by JTAG control.
The
ioc
register (see
Table 54 on page 99
) is cleared after reset, including its EBIO field that controls the multiplexing of the VEC0/IOBIT7,
VEC1/IOBIT6, VDC2/IOBIT5, and VEC3/IOBIT4 pins. After reset, these pins are configured as the VEC[3:0] outputs and are logic high.
If unused, this pin must be pulled low through a 10 k
resistor to V
