Can I use a value other than 4.7 kΩ ± 10% for pull-up?

Latest Updated:03/24/2009

Question:

To connect the E8a emulator to the MCU, the value of a pull-up resistor to be connected to the MODE pin of the MCU is specified as 4.7 kΩ ± 10% in the hardware manual. Can I use a value other than this for pull-up?

Answer:

The pull-up resistance of 4.7 kΩ ± 10% was calculated as the value necessary to obtain an “H” (high) level, based on the internal circuit of the E8a emulator and the DC characteristics of the MCU. If a value other than this constant is used for pull-up, the E8a emulator may not operate correctly.
