AMAC on PB not responding properly

  • Description: PB is used to control LV/HV. After configuring AMAC, there is current drop in power supply (which is good); while there is no current change in PS after turning on LV/HV (e->LV/HVOn()).
  • Solution: change the AMAC_SPEED to 1kHz in stlib/amac1.h (0x0010-->0x0020).
