Change of Transmit DMO (Drive Monitor Output) Condition
Interrupt Status:
This RESET-upon-READ bit indicates whether or not the “Change of
the Transmit DMO Condition” Interrupt has occurred since the last
read of this register.
0 = Indicates that the “Change of the Transmit DMO Condition”
Interrupt has NOT occurred since the last read of this register.
1 = Indicates that the “Change of the Transmit DMO Condition”
Interrupt has occurred since the last read of this register.
This bit is set to a “1” every time when DMO_n status bit (bit 6
of Register 0x0Fn5) has changed since the last read of this
register.

OTE
:
Users can determine the current state of the “Transmit DMO
Condition” by reading out the content of bit 6 within Register
0x0Fn5
