Type Alias rp2040_pac::i2c0::ic_sar::IC_SAR_R

pub type IC_SAR_R = FieldReader<u16>;

Field IC_SAR reader - The IC_SAR holds the slave address when the I2C is operating as a slave. For 7-bit addressing, only IC_SAR[6:0] is used.

This register can be written only when the I2C interface is disabled, which corresponds to the IC_ENABLE[0] register being set to 0. Writes at other times have no effect.

Note: The default values cannot be any of the reserved address locations: that is, 0x00 to 0x07, or 0x78 to 0x7f. The correct operation of the device is not guaranteed if you program the IC_SAR or IC_TAR to a reserved value. Refer to <<table_I2C_firstbyte_bit_defs>> for a complete list of these reserved values.
