Type Alias rp2040_pac::i2c0::IC_DATA_CMD

pub type IC_DATA_CMD = Reg<IC_DATA_CMD_SPEC>;

IC_DATA_CMD (rw) register accessor: I2C Rx/Tx Data Buffer and Command Register; this is the register the CPU writes to when filling the TX FIFO and the CPU reads from when retrieving bytes from RX FIFO.

The size of the register changes as follows:

Write: - 11 bits when IC_EMPTYFIFO_HOLD_MASTER_EN=1 - 9 bits when IC_EMPTYFIFO_HOLD_MASTER_EN=0 Read: - 12 bits when IC_FIRST_DATA_BYTE_STATUS = 1 - 8 bits when IC_FIRST_DATA_BYTE_STATUS = 0 Note: In order for the DW_apb_i2c to continue acknowledging reads, a read command should be written for every byte that is to be received; otherwise the DW_apb_i2c will stop acknowledging.

You can read this register and get ic_data_cmd::R. You can reset, write, write_with_zero this register using ic_data_cmd::W. You can also modify this register. See API.
