This bit indicates whether there is an interrupt generated in channel 0.
0: No interrupt is generated or all the interrupts are cleared in channel 0. (default)
1: At least one interrupt is generated in channel 0.
Reserved.
Reserved.
This bit is valid only when the TMOV_IM bit (b0, GCF) is ‘0’. This bit indicates the interrupt status of one second time over.
0: No one second time over interrupt is generated; or a ‘1’ is written to this bit. (default)
1: One second time over interrupt is generated and is reported by the INT pin.
