Notes: 1. Applies to input pins MEOR, MWS0 to MWS5, DUTY, SHL, ',632)), M/6, 5(6(7, and CR,

and when inputting to input/output pins CL1, FLM, '2&, and M.

2. Applies when outputting from input/output pins CL1, FLM, '2&, and M.

3. Applies to V1L/R, V2L/R, V5L/R, and V6L/R. X1 to X240 are open.

7. Input and output currents are excluded. When a CMOS input is floating, excess current flows

from the power supply through to the input circuit. To avoid this, VIH and VIL must be held to

VCC and GND levels, respectively.

8. This value is specified for the current flowing through GND under the following conditions:

Internal oscillation circuit is used. Each terminal of MEOR, MWS0 to MWS5, DUTY, SHL,

',632)), M/6, and 5(6(7 is connected to VCC. Oscillator is set as described in note 6.
