Whenever this counter overflows, values from DAC_LEFT and DAC_RIGHTare read and a DAC interrupt is generated.10.7 GPIO RegistersGPIO registers, prefix GPIO_Reg Type Reset Abbrev[bits] Description0xC017 rw 0 DDR[3:0] Direction.0xC018 r 0 IDATA[3:0] Values read from the pins.0xC019 rw 0 ODATA[3:0] Values set to the pins.GPIO_DIR is used to set the direction of the GPIO pins. 1 means output. GPIO_ODATAremembers its values even if a GPIO_DIR bit is set to input.GPIO registers don’t generate interrupts.Note that in VS1003 the VSDSP registers can be read and written through the SCI_WRAMADDRand SCI_WRAM registers. You can thus use the GPIO pins quite conveniently.Version: 1.06, 2012-03-16 47
