  Ko te ahua 73 e whakaatu ana i te whirihoranga putanga o te moka tauranga I/O.

Pūtau utu I/O

Ka whakamahia tenei pūtau ki te whakahaere i te reiti mate whakawhiti I/O (tfall / trise) hei whakaiti i te haruru I/O i runga i te tuku hiko.

Kua wehea te pūtau ki nga poraka e rua:

• Ko te poraka tuatahi he tohu tino pai mo te PVT o naianei. Ka taea te panui te waehere kei roto i tenei paraka ina whakaritea te haki READY o te SYSCFG_CCSR.
• Ko te poraka tuarua e whakahaere ana i te reiti mate I/O. Ka whiriwhiria e te kaiwhakamahi te waehere hei tono me te whakarite ma te rorohiko.

Ko te pūtau utu I/O he 2 voltage awhe: 1.62 ki te 2.0 V me te 2.7 ki te 3.6 V.

whirihoranga mahi rereke

Ina whakaritea te tauranga I/O hei mahi rereke:

• Ka taea te whirihora i te parepare whakaputa i roto i te aratau-a-tuwhera, i te aratau pana-kumea ranei
• Ko te kaitapa whakaputa ka peia e nga tohu ka puta mai i te peripheral (ka taea te whakawhiti me te raraunga)
• Kua whakahohehia te urunga keu a Schmitt
• Ko nga parenga kume me te kume-iho ngoikore ka whakahohehia, kaore ranei i runga i te uara o te rehita GPIOx_PUPDR
• Ko nga raraunga kei runga i te titi I/O he sampi arahina ki te rehita raraunga whakauru ia huringa karaka AHB
• Ma te panui panui ki te rehita raraunga whakauru ka whiwhi te ahua I/O
  Ko te ahua 74 e whakaatu ana i te whirihoranga mahi rereke o te moka tauranga I/O.

whirihoranga tairitenga

Ina whakaritea te tauranga I/O hei whirihoranga tairitenga:

• Kua monoa te parepare whakaputa
• Kua whakakorehia te urunga keu a Schmitt, e kore e kai mo ia uara tairitenga o te titi I/O. Ko te putanga o te keu a Schmitt ka pehia ki te uara tonu (0).
• Ko nga parenga kume-ake me te kume-iho ngoikore kua monokia e te taputapu
• Panui te uru ki te rehita raraunga whakauru ka whiwhi te uara "0"
  Ko te ahua 75 e whakaatu ana i te whirihoranga-impedance teitei, tairitenga-whakauru o nga paraka tauranga I/O.

Ko etahi titi/poi e hono tika ana ki te PA0_C, PA1_C, PC2_C me te PC3_C ADC whakaurunga tairitenga (tirohia te Whakaahua 76): he ara tika kei waenganui i nga titi/poi Pxy_C me Pxy, na roto i te whakahuri tairitenga (tirohia te Wahanga 12.3.1: SYSCFG rehita whirihoranga aratau papaahuri (SYSCFG_PMCR) mo nga korero mo te whirihora i nga huringa tairitenga).

Ko te VDD_FT he mea motuhake mo te 5V I/Os. He rereke mai i te VDD.

Ma te whakamahi i nga titi oscillator HSE, LSE ranei hei GPIO

• Ina whakawetohia te HSE, LSE oscillator ranei (te ahua taunoa i muri i te tautuhi), ka taea te whakamahi i nga titi oscillator e pa ana hei GPIO noa.
• Ina whakakāhia te HSE, LSE oscillator ranei (ma te whakatakoto i te moka HSEON, LSEON ranei i roto i te rehita RCC_CSR) ka riro ma te oscillator te mana o ona titi e hono ana, karekau he painga o te whirihoranga GPIO o enei titi.
• Ina whirihorahia te oscillator i roto i te aratau karaka o waho o te kaiwhakamahi, ko te pine OSC_IN, OSC32_IN anake ranei ka waiho mo te whakauru karaka ka taea tonu te whakamahi i te pine OSC_OUT, OSC32_OUT ranei hei GPIO noa.

Ma te whakamahi i nga titi GPIO i roto i te rohe tuku taapiri

Ka ngaro te mahi PC13/PC14/PC15/PI8 GPIO i te wa e whakawetohia ana te rohe tuku matua (ina ka uru te taputapu ki te aratau Standby). I tenei keehi, ki te kore to raatau whirihoranga GPIO e tukuna e te whirihoranga RTC, ka whakatakotoria enei titi ki te aratau whakauru tairitenga.
