Section 16 I
16.4.7
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 16.19 shows the IRIC set timing and SCL control.

IRIC Setting Timing and SCL Control
(a) When WAIT = 0, and FS = 0 or FSX = 0 (I
(b) When WAIT = 1, and FS = 0 or FSX = 0 (I
(c) When FS = 1 and FSX = 1 (synchronous serial format)
