Hi,
Im using P1[17] as out_control for MM74HC573.
When i first connect the voltage or reset the system, i am getting voltage 2[v] ( ONly voltage above 3[v] means '1')
This is a big problem. i need the value to be '1' (or '0').
How can i solves this?
I've tried some actions:
- Disabled the P1[17] ENET-MDIO option
- Tried to write directly to the register- no effect
- Tried to connect pull up resistor.
Could someone help in this please?
By the way,
I have already a system that works perfect when i use the P0[26] for outcontrol.
