Peripheral Interface 3.1 General Purpose Input / Output Interface (GPIO) TR6260 has up to 18 GPIO pins which can be assigned to various functions by programming the appropriate registers. There are several kinds of GPIOs:

digital only GPIOs, analog enabled GPIOs, capacitive touch enabled GPIOs, etc. Analog enabled GPIOs can be configured as digital GPIOs. Capacitive touch enabled GPIOs can be configured as digital GPIOs. Each digital enabled GPIO can be configured to internal pull-up or pull-down, or set to high impedance. When configured as an input, the input value can be read through the register. The input can also be set to edge-trigger or level-trigger to generate CPU interrupts. In short, the digital IO pins are bi-directional, non-inverting and tri-state, including input and output buffer with tri-state control. These pins can be multiplexed with other functions, such as the SDIO interface, UART, SPI, etc. For low power operations, the GPIOs can be set to hold their states. Beijing Eswin Technology Co.,Ltd 3.2 Analog-to-Digital Converter (ADC) TR6260 integrates 12-bit SigmaDelta ADCs and supports measurements on 4 channels (analog enabled pins) to sample battery voltage, temperature sensor and external analog input. 3.3 SD/SDIO/MMC Host Controller This SDIO can act as SDIO/SD/MMC device, with connecting to SDIO host.
