22.4.18 I2C Host Input Delay Compensation Register
Note:
- The default value is 0x0012, assumed UPB clock is 50 MHz and path delay is 360 ns with 2.3V and 1.1K pull-up resistance (worst case).

Bit 31 – HIDLYCEN I2C Host Input Delay Compensation Enable bit
| Value | Description |
|---|---|
| 1 | Programmable hardware host input delay compensation is enabled (default). |
| 0 | Fixed hardware host input delay compensation is used. |
Bits 15:0 – HIDLYC[15:0] Host Input Delay Compensation Value bits(1)
These bits are used to compensate for input path delays for the Host mode sampling point.
The delay is calculated as follows: HIDLYC value x I2C UPB CLK time.
