Struct rp2040_pac2::i2c::regs::IcFsSpklen

#[repr(transparent)]pub struct IcFsSpklen(pub u32);

I2C SS, FS or FM+ spike suppression limit This register is used to store the duration, measured in ic_clk cycles, of the longest spike that is filtered out by the spike suppression logic when the component is operating in SS, FS or FM+ modes. The relevant I2C requirement is tSP (table 4) as detailed in the I2C Bus Specification. This register must be programmed with a minimum value of 1.

Implementations

impl IcFsSpklen

pub const fn ic_fs_spklen(&self) -> u8

This register must be set before any I2C bus transaction can take place to ensure stable operation. This register sets the duration, measured in ic_clk cycles, of the longest spike in the SCL or SDA lines that will be filtered out by the spike suppression logic. 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. The minimum valid value is 1; hardware prevents values less than this being written, and if attempted results in 1 being set. or more information, refer to ‘Spike Suppression’.

pub fn set_ic_fs_spklen(&mut self, val: u8)

This register must be set before any I2C bus transaction can take place to ensure stable operation. This register sets the duration, measured in ic_clk cycles, of the longest spike in the SCL or SDA lines that will be filtered out by the spike suppression logic. 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. The minimum valid value is 1; hardware prevents values less than this being written, and if attempted results in 1 being set. or more information, refer to ‘Spike Suppression’.
