Additional Information

There are two main types of PCM128

Hi-Vol

• 1024K Flash
• NO Parallel EEprom (PROD style)
• 32K Serial EE
• 36K RAM

Lo-Vol

• 1024K Flash
• Parallel EEProm (DEV Style)
• 32K Serial EE
• 1024K RAM

Tips

• Think of EST1-12 and EST13-16 as two separate banks
• Avoid mixing Behaviours within a bank where possible, as it can potentially restrict DriverModes and Diagnostic Capability.

FAQ

What's special about EST13 to EST16?

• These pins have stronger LowSide Drivers and can sync higher current
• The hardware can be configured as PUSH_PULL or LOW_SIDE drive
• Current MotoHawk (0.8.4b8) Sets the DriverMode to LOW_SIDE for DIO, OneShot but PUSH_PULL for PWM.
• The Hi-Vol PCM128 does not have pull-up transistors, so technically cannot be configured as PUSH_PULL but the polarity remains active high.
• When instantiating from ControlCore as a LOW_SIDE it makes them active low instead of active high.

Why am I getting a ERROR_DRIVER_CONFLICT?

See ERROR_DRIVER_CONFLICT

Where have DG5, 6,7,8 Gone?

You will get "Hardware Not Supported" if you use a Low-Vol. These resources are consumed as part of the KNOCK2 device.

Where is my KNOCK2?

The Hi-Vol only has KNOCK1
