Section 15 I
Bit 6—Normal Stop Condition Detection Flag (STOP): Indicates that a stop condition has been
detected after completion of frame transfer in I
Bit 5—I
(IRTR): Indicates that the I
source is completion of reception/transmission of one frame in continuous transmission/reception
for which DTC activation is possible. When the IRTR flag is set to 1, the IRIC flag is also set to 1
at the same time.
IRTR flag setting is performed when the TDRE or RDRF flag is set to 1. IRTR is cleared by
reading IRTR after it has been set to 1, then writing 0 in IRTR. IRTR is also cleared automatically
when the IRIC flag is cleared to 0.
