SDA Hold and Mode Switch Delay Timing Register (DWC_mipi_i3c_HCI_block.SDA_HOLD_SWITCH_DLY_TIMING) – Offset 230
SDA Hold and Mode Switch Delay Timing Register
The Bits [2:0] of this register are used to shift the sda_out with respect to sda_oe while switching transfer from Open Drain timing to
Push Pull timing.
The bits [10:8] of this register are used to shift the sda_oe with respect to sda_out while switching transfer from Pus pull timing to
Open Drain timing.
The bits [18:16] of this register are used to control the hold time of SDA during transmit mode in SDR and DDR transfers.
