FLAG REGISTER (T_FLAGR)
R254 - Read/Write
Register Page: 10
Reset value: 0000 0000 (00h)
Bit 7 = CP0: Capture 0 flag.
This bit is set by hardware after a capture on
REG0R register. An interrupt is generated de-
pending on the value of the GTIEN, CP0I bits in
the IDMR register and the A0 bit in the T_FLAGR
register. The CP0 bit must be cleared by software.
Setting by software acts as a software load/cap-
ture to/from the REG0R register.
0: No Capture 0 event
1: Capture 0 event occurred
Bit 6 = CP1: Capture 1 flag.
This bit is set by hardware after a capture on
REG1R register. An interrupt is generated de-
pending on the value of the GTIEN, CP0I bits in
the IDMR register and the A0 bit in the T_FLAGR
register. The CP1 bit must be cleared by software.
Setting by software acts as a capture event on the
REG1R register, except when in Bicapture mode.
0: No Capture 1 event
1: Capture 1 event occurred
Bit 5 = CM0: Compare 0 flag.
This bit is set by hardware after a successful com-
pare on the CMP0R register. An interrupt is gener-
ated if the GTIEN and CM0I bits in the IDMR reg-
ister are set. The CM0 bit is cleared by software.
0: No Compare 0 event
1: Compare 0 event occurred
Bit 4 = CM1: Compare 1 flag.
This bit is set after a successful compare on
CMP1R register. An interrupt is generated if the
208/430

GTIEN and CM1I bits in the IDMR register are set.
The CM1 bit is cleared by software.
0: No Compare 1 event
1: Compare 1 event occurred
Bit 3 = OUF: Overflow/Underflow.
This bit is set by hardware after a counter Over/
Underflow condition. An interrupt is generated if
GTIEN and OUI=1 in the IDMR register. The OUF
bit is cleared by software.
0: No counter overflow/underflow
1: Counter overflow/underflow
Bit 2 = OCP0: Overrun on Capture 0.
This bit is set by hardware when more than one
INT/DMA requests occur before the CP0 flag is
cleared by software or whenever a capture is sim-
ulated by setting the CP0 flag by software. The
OCP0 flag is cleared by software.
0: No capture 0 overrun
1: Capture 0 overrun
Bit 1 = OCM0: Overrun on compare 0.
This bit is set by hardware when more than one
INT/DMA requests occur before the CM0 flag is
cleared by software.The OCM0 flag is cleared by
software.
0: No compare 0 overrun
1: Compare 0 overrun
Bit 0 = A0: Capture interrupt function.
This bit is set and cleared by software.
0: Configure the capture interrupt as an OR func-
1: Configure the capture interrupt as an AND func-
Note: When A0 is set, both CP0I and CP1I in the
IDMR register must be set to enable both capture
interrupts.
