Overview 1.5 Pin Functions Table 1.14 Pin functions (1/3) Function Signal I/O Description Power supply VCC Input Power supply pin. Connect it to the system power supply. Connect this pin to VSS by a 0.1-μF capacitor. The capacitor should be placed close to the pin. VCL Input Connect this pin to the VSS pin by the smoothing capacitor used to stabilize the internal power supply. Place the capacitor close to the pin. VSS Input Ground pin. Connect it to the system power supply (0 V). Clock XTAL Output Pins for a crystal resonator. An external clock signal can be input through the EXTAL pin. EXTAL Input XCIN Input Input/output pins for the sub-clock oscillator. Connect a crystal resonator between XCOUT and XCIN. XCOUT Output CLKOUT Output Clock output pin. Operating mode control MD Input Pins for setting the operating mode. The signal levels on these pins must not be changed during operation mode transition at the time of release from the reset state. System control RES Input Reset signal input pin. The MCU enters the reset state when this signal goes low. CAC CACREF Input Measurement reference clock input pin. On-chip debug SWDIO I/O Serial Wire debug Data Input/Output pin. SWCLK Input Serial Wire Clock pin. Interrupt NMI Input Non-maskable interrupt request pin. IRQ0 to IRQ7 Input Maskable interrupt request pins. GPT GTETRGA, GTETRGB Input External trigger input pin. GTIOC0A to GTIOC6A, GTIOC0B to GTIOC6B I/O Input capture, Output Compare, or PWM output pin. GTIU Input Hall sensor input pin U. GTIV Input Hall sensor input pin V. GTIW Input Hall sensor input pin W. GTOUUP Output Three-phase PWM output for BLDC motor control (positive U phase). GTOULO Output Three-phase PWM output for BLDC motor control (negative U phase). GTOVUP Output Three-phase PWM output for BLDC motor control (positive V phase). GTOVLO Output Three-phase PWM output for BLDC motor control (negative V phase). GTOWUP Output Three-phase PWM output for BLDC motor control (positive W phase). GTOWLO Output Three-phase PWM output for BLDC motor control (negative W phase). AGT AGTEE0, AGTEE1 Input External event input enable. AGTIO0, AGTIO1 I/O External event input and pulse output. AGTO0, AGTO1 Output Pulse output. AGTOA0, AGTOA1 Output Output compare match A output. AGTOB0, AGTOB1 Output Output compare match B output. RTC RTCOUT Output Output pin for 1-Hz/64-Hz clock. |
