* Question
| What is the SDA output? |
* Answer
| The value of bit 7 to bit 0 (D7 to D0) written in the UiTB register is sequentially output from D7, and the 9th bit (D8) is ACK or NACK.The initial value of the SDAi transmission output must be set in the state where IICM=1 (12C mode) and the SMD2 to SMD0 bits of the UiMR register are “000b” (serial interface is invalid).In addition, the SDH1 bit cannot be written at the rising edge timing of the UARTi transfer clock because it is possible to make the ABT bit “1” (detect). |
