Häufig gestellte Fragen / What is the default state of General Purpose Input/Output (GPIO) after reset?
https://www.nuvoton.com.cn/support/technical-support/faq/d429a5dc-04f1-11ea-b113-05daf7eedf03/
What is the default state of General Purpose Input/Output (GPIO) after reset? 1423563022188 The default state of GPIO after reset may vary depending on the product series. The state of GPIO for M051 BN and NUC100 Series is in Quasi-bidirectional mode with weakly pull-high resistor (110 kΩ~300 kΩ), and the state of GPIO for Mini51 and Nano100 Series is in Input mode. However, the state of GPIO for M051 DN/DE and NUC200 Series depends on the setting of CIOINI (Config0[10]). If CIOINI is set to 1, all pins will be in Quasi-bidirectional mode after reset. If CIOINI is cleared to 0, all pins will be Input mode after reset.

Bietet die NuMicro™-Familie den Taktausgangskontakt zur Messung des internen oder externen Takts? 1388505600000 Ja, das hängt jedoch von der Teilenummer ab. Die Messungsfrequenz ist Fin/21 bis Fin/216, wobei Fin die Eingangstaktfrequenz zum Taktteiler ist. Bitte prüfen Sie die Kontaktkonfiguration und ziehen sie entsprechende technische Referenzanleitung zurate. Bitte beachten Sie Folgendes zur Messung des internen oder externen Takts vom Taktausgangskontakt (CLKO). Beispiel: (NUC100-Serie) /* GPIO-Kontakt als CLKO-Kontakt festlegen */ SYS->GPBMFP.CPO0_CLKO_AD0 = 1; SYS->ALTMFP.PB12_CLKO = 1; /* Frequenzteilerausgang */ SYSCLK->CLKSEL2.FRQDIV_S = 0; // Fin-Quellen wählen 12 MHz SYSCLK->APBCLK.FDIV_EN = 1; // FRQDIV_CLK aktivieren SYSCLK->FRQDIV.FDIV_EN = 1; // Teiler aktivieren SYSCLK->FRQDIV.FSEL = 0; // CLKO = Fin / 2(N+1)
