Struct rp2040_pac::i2c0::ic_slv_data_nack_only::IC_SLV_DATA_NACK_ONLY_SPEC

pub struct IC_SLV_DATA_NACK_ONLY_SPEC;

Generate Slave Data NACK Register

The register is used to generate a NACK for the data part of a transfer when DW_apb_i2c is acting as a slave-receiver. This register only exists when the IC_SLV_DATA_NACK_ONLY parameter is set to 1. When this parameter disabled, this register does not exist and writing to the register’s address has no effect.

A write can occur on this register if both of the following conditions are met: - DW_apb_i2c is disabled (IC_ENABLE[0] = 0) - Slave part is inactive (IC_STATUS[6] = 0) Note: The IC_STATUS[6] is a register read-back location for the internal slv_activity signal; the user should poll this before writing the ic_slv_data_nack_only bit.

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