16.3.6

IRIC Setting Timing and SCL Control

The interrupt request flag (IRIC) is set at different times depending on the WAIT bit in ICMR, the

FS bit in SAR, and the FSX bit in SARX. If the TDRE or RDRF internal flag is set to 1, SCL is

automatically held low after one frame has been transferred; this timing is synchronized with the

internal clock. Figure 16.11 shows the IRIC set timing and SCL control.
