36.2.15 Global Transmit Interrupt Status Register (GTINTSTS)
All flags in the GTINTSTS register become 0 in global reset or channel reset mode.
TSIF0 Flag (RSCAN0 Transmit Buffer Interrupt Status Flag)
The TSIF0 flag becomes 1 when the TMIEC.TMIEp bit is set to 1 (enabling interrupts) and the corresponding
TMSTSp.TMTRF[1:0] flags become 10b (transmission has been completed without transmit abort request) or 11b
(transmission has been completed with transmit abort request).
This flag becomes 0 when all TMSTSp.TMTRF[1:0] flags that satisfy a condition for setting the TSIF0 flag to 1 are set
to 00b. This flag also becomes 0 when the TMIEC.TMIEp bit is set to 0.
TAIF0 Flag (RSCAN0 Transmit Buffer Abort Interrupt Status Flag)
The TAIF0 flag becomes 1 when the CTRH.TAIE bit is set to 1 (enabling interrupts) and the TMSTSp.TMTRF[1:0]
flags become 01b (transmit abort has been completed).
This flag becomes 0 when the TMSTSp.TMTRF[1:0] flags, which indicate that the abort of transmission has been
completed, are set to 00b.
CFTIF0 Flag (RSCAN0 Transmit/Receive FIFO Interrupt Status Flag)
The CFTIF0 flag becomes 1 when the CFCCL0.CFTXIE bit is set to 1 (enabling interrupts) and the CFSTS0.CFTXIF
flag becomes 1 (interrupt request present).
This flag becomes 0 when the CFSTS0.CFTXIF flag is set to 0. This flag also becomes 0 when the CFCCL0.CFTXIE bit
is set to 0.
THIF0 Flag (RSCAN0 Transmit History Interrupt Status Flag)
The THIF0 flag becomes 1 when the THLCC0.THLIE bit is set to 1 (enabling interrupts) and the THLSTS0.THLIF flag
becomes 1 (interrupt request present).
This flag becomes 0 when the THLSTS0.THLIF flag is set to 0. This flag also becomes 0 when the THLCC0.THLIE bit
is set to 0.
