When Using a PLL Oscillator Circuit: Keep the wiring short from the PLL V_CC and V_SS
connection pattern to the power supply pins, and make the pattern width large, to minimize the
inductance component. Ground the oscillation stabilization capacitors C1 and C2 to V_SS (PLL1)
and V_SS (PLL2), respectively. Place C1 and C2 close to the CAP1 and CAP2 pins and do not
locate a wiring pattern in the vicinity.

3.3 Bus Width of the CS0 Area
Pins MD3 and MD4 are used to specify the bus width of the CS0 area. The pin combination and
functions are listed in table 3.6. Do not switch the MD4 and MD3 pins while they are operating.
Switching them will cause operating errors.
