Struct rp2040_pac2::i2c::regs::IcSsSclLcnt

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

Standard Speed I2C Clock SCL Low Count Register

Implementations

impl IcSsSclLcnt

pub const fn ic_ss_scl_lcnt(&self) -> u16

This register must be set before any I2C bus transaction can take place to ensure proper I/O timing. This register sets the SCL clock low period count for standard speed. For more information, refer to ‘IC_CLK Frequency Configuration’ 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 8; hardware prevents values less than this being written, and if attempted, results in 8 being set. For designs with APB_DATA_WIDTH = 8, the order of programming is important to ensure the correct operation of DW_apb_i2c. The lower byte must be programmed first, and then the upper byte is programmed.
