When is PM22 set to 1 when the serial interface is used?

Latest Updated:04/01/2006

Question:

When is PM22 set to 1 when the serial interface is used?

Answer:

In the V850E/MS1, PM2 becomes FFH when reset is released.
Therefore, if PM22 retains the initial value, you don't have to do anything.
If it is necessary to make a setting, we recommended that you first set the value to P2 and then make the setting before the serial setting is made (to prevent undefined output to pins set as output ports by other bits, the setting should be made after P2 data is set).
