Bidirectional Data Register Input Buffer Full
Set to 1 when the host processor writes to TWR15.
This is an internal interrupt source to the slave
processor (this LSI). IBF3B is cleared to 0 when the
slave processor reads TWR15.
0: [Clearing condition]
When the slave processor reads TWR15
1: [Setting condition]
When the host processor writes to TWR15 using I/O
write cycle
Bidirectional Data Register Output Buffer Full
Set to 1 when the slave processor (this LSI) writes to
TWR15. OBF3B is cleared to 0 when the host
processor reads TWR15.
0: [Clearing condition]
When the host processor reads TWR15 using I/O
read cycle, or the slave processor writes 0 to the
OBF3B bit
1: [Setting condition]
When the slave processor writes to TWR15
Master Write Mode Flag
Set to 1 when the host processor writes to TWR0.
MWMF is cleared to 0 when the slave processor
(this LSI) reads TWR15.
0: [Clearing condition]
When the slave processor reads TWR15
1: [Setting condition]
When the host processor writes to TWR0 using I/O
write cycle while SWMF = 0
