PIN FUNCTIONS
RCIN. A precision resistor is connected between this pin Port 0 (P07-P00). Port 0 is an 8-bit, CMOS-compatible
and the power supply to form the precision RC oscillator. open-drain output (Figure 7).

CLKOUT. This pin is the system clock of the Z8^® and runs
at the frequency of the RC oscillator (Test only).
