MCKIN
- Using an external clock :
X1 is connected to GND with MCKIN connected to the input of the external clock
- Using XTAL :
MCKIN is connected to VDD with X1, X2 connected to the Crystal Oscillator
User Setup Pins
Setup pins are strapped high or low to configure options according to system design. For low, strap to
ground. Many pins have internal pullups on their input buffers. These pins can be left unconnected to keep
them in high state.
CPU Type Selection
(nRWM: Pin)
In Peripheral mode, this pin selects the CPU type; in this case, the definition of nWR/DIR (pin) and
nRD/nDS (pin) are selected. (Refer to Figure 3 - MOTOROLA CPU Mode (68hXX) and Figure 4 - INTEL
CPU MODE (86XX).
