Register 10: I

C Master Clock Low Timeout Count (I2CMCLKOCNT), offset
0x024
This register contains the upper 8 bits of a 12-bit counter that can be used to keep the timeout limit
for clock stretching by a remote slave. The lower four bits of the counter are not user visible and
are always 0x0.
Note: The Master Clock Low Timeout counter counts for the entire time SCL is held Low
continuously. If SCL is deasserted at any point, the Master Clock Low Timeout Counter is
reloaded with the value in the I2CMCLKOCNT register and begins counting down from this
value.
