Hi team,
My customer has some issue about MCF8316A,
Could you please give me some advice on these questions.
and I give some comments on my customer questions, but I am not sure if I am right or wrong, please help me check.
Below figure is the schematic of MCF8316A
1.) How to connect the pin EXT_WD/EXT_CLK/ ALARM
[Me]: for EXT_WD/EXT_CLK => connect to the control interface. (I2C)
for ALARM => Open-drain output requires an external pull-up resistor to 1.8V to 5.0V. Or leave this pin floating.
2.) Should I connect Pin BRAKE/DIR/DRVOFF via I2C Register
[Me]: If you need to control this pin, you should connect it via I2C register.
3.) Could you help me to check if SPEED( to DDP442X CW_PWM) / nFlAULT (to DDP442X PMD_INTZ) connect correct?
[Me]: Both SPEED and nFlAULT are controlled by control interface, I do not understand why my customer need to put the resistor in there. is this correct or my customer should remove it.
4.) My customer replace PMD1000 to MCF8316A, but MCF8316A do not have CWCTR signal ,does my customer need to remove it?
