Is clock stretching to be expected when clocking an I2C slave interface at 400 KHz?  Using LPC54102.  Wondering if it indicates a configuration issue.

LPC54102

I2C0 slave

Using the I2C config and interrupt handler from LPCOpen periph_i2cs_interrupt demo

Using a master at 400 KHz, I see clocking stretching for every ACK, don't see it at 100 KHz.

I2C CLKDIV = 2
