hi, where can i get RM44L920APGE register table? could i set the pin51 MIBSPI3SOMI[0]/AWM1_EXT_ENA/ECAP2 as a GPIO?

    Hello,
    You can set pin51 as GPIO when in MibSPI mode. You can see terminal configuration ans functions in Datasheet (page 18 for pin51 in MibSPI mode).

    Hi, I see the introduction of GIOA and GIOB in the datasheet, all GIOA and GIOB can be interrupts, can I set pin51 as a GIOA or G
    IOB, what is the difference between GIOA,B and GPIOs? the description in the datasheet of "xxxxxxxx or GIO" means these pins can be seperately set as a GPIO, is it right? thanks.

    Hello,
    pin 51 can not be muxed as GIOA or GIOB.
    In your particular case, pin 51 (MIBSPI3SOMI[0]/AWM1_EXT_ENA/ECAP2) can be set as GIO using HALCoGen as follows: You should go to SPI3-->SPI3 Port tab and set SOMI Pin Mode to be GIO and its direction. After that in PINMUX tab MIBSPI3SOMI has to be set for pin 51. Then from Driver enable tab GIO and SPI3 drivers needs to be enabled. After HALCoGen generates code you can use gio.c functions. For example: gioToggleBit(spiPORT3, 11); Both gio and spi modules must be initialized (gioInit(); spiInit();) first.
