Bit 7—Error Stop Condition Detection Flag (ESTP): Indicates that a stop condition has been
detected during frame transfer in I²C bus format slave mode.
Bit 7
ESTP
0
1
Description
No error stop condition
[Clearing conditions]
1. When 0 is written in ESTP after reading ESTP = 1
2. When the IRIC flag is cleared to 0
• In I²C bus format slave mode
Error stop condition detected
[Setting condition]
When a stop condition is detected during frame transfer
• In other modes
No meaning
(Initial value)
Bit 6—Normal Stop Condition Detection Flag (STOP): Indicates that a stop condition has been
detected after completion of frame transfer in I²C bus format slave mode.
Bit 6
STOP
0
1
Description
No normal stop condition
(Initial value)
[Clearing conditions]
1. When 0 is written in STOP after reading STOP = 1
2. When the IRIC flag is cleared to 0
• In I²C bus format slave mode
Normal stop condition detected
[Setting condition]
When a stop condition is detected after completion of frame transfer
• In other modes
No meaning
Bit 5—I²C Bus Interface Continuous Transmission/Reception Interrupt Request Flag
(IRTR): Indicates that the I²C bus interface has issued an interrupt request to the CPU, and the
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.
