11.6.7 Universal Digital Blocks (UDBs)
PSoC Creator provides a library of pre-built and tested standard digital peripherals (UART, SPI, LIN, PRS, CRC, timer, counter, PWM,
AND, OR, and so on) that are mapped to the UDB array. See the component data sheets in PSoC Creator for full AC/DC specifications,
APIs, and example code.
