2.4.3 VDD1, VSS1, VSS2 — Core Power Pins
VDD1, VSS1 and VSS2 are the core power and ground pins and related to the voltage regulator output.
These pins serve as connection points for filter capacitors. VSS1 and VSS2 are internally connected.
2.4.4 VDDA, VSSA — Power Supply Pins for ATD and VREG
VDDA, VSSA are the power supply and ground pins for the voltage regulator and the analog to digital
converter.
2.4.5 VDDM1, VDDM2, VDDM3 — Power Supply Pins for Motor 0 to 5
VDDM1, VDDM2 and VDDM3 are the supply pins for the ports U,V and W. VDDM1, VDDM2 and
VDDM3 are internally connected.
2.4.6 VSSM1, VSSM2, VSSM3 — Ground Pins for Motor 0 to 5
VSSM1, VSSM2 and VSSM3 are the ground pins for the ports U,V and W. VSSM1, VSSM2 and VSSM3
are internally connected.
2.4.7 VLCD — Power Supply Reference Pin for LCD driver
VLCD is the voltage reference pin for the LCD driver. Adjusting the voltage on this pin will change the
display contrast.
2.4.8 VRH, VRL — ATD Reference Voltage Input Pins
VRH and VRL are the voltage reference pins for the analog to digital converter.
2.4.9 VDDPLL, VSSPLL — Power Supply Pins for PLL
VDDPLL and VSSPLL are the PLL supply pins and serve as connection points for external loop filter
components.
