Bit Name Reset Access Description
23:19 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
18 ICV2 0 R CC2 Input Capture Valid
This bit indicates that TIMERn_CC2_CCV contains a valid capture value. These bits are only used in input capture mode and are
cleared when CCMODE is written to 0b00 (Off).
Value Description
0 TIMERn_CC2_CCV does not contain a valid capture value(FIFO empty)
1 TIMERn_CC2_CCV contains a valid capture value(FIFO not empty)
17 ICV1 0 R CC1 Input Capture Valid
This bit indicates that TIMERn_CC1_CCV contains a valid capture value. These bits are only used in input capture mode and are
cleared when CCMODE is written to 0b00 (Off).
Value Description
0 TIMERn_CC1_CCV does not contain a valid capture value(FIFO empty)
1 TIMERn_CC1_CCV contains a valid capture value(FIFO not empty)
16 ICV0 0 R CC0 Input Capture Valid
This bit indicates that TIMERn_CC0_CCV contains a valid capture value. These bits are only used in input capture mode and are
cleared when CCMODE is written to 0b00 (Off).
Value Description
0 TIMERn_CC0_CCV does not contain a valid capture value(FIFO empty)
1 TIMERn_CC0_CCV contains a valid capture value(FIFO not empty)
15:11 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
10 CCVBV2 0 R CC2 CCVB Valid
This field indicates that the TIMERn_CC2_CCVB registers contain data which have not been written to TIMERn_CC2_CCV. These
bits are only used in output compare/pwm mode and are cleared when CCMODE is written to 0b00 (Off).
Value Description
0 TIMERn_CC2_CCVB does not contain valid data
1 TIMERn_CC2_CCVB contains valid data which will be written to TIMERn_CC2_CCV on the next update event
9 CCVBV1 0 R CC1 CCVB Valid
This field indicates that the TIMERn_CC1_CCVB registers contain data which have not been written to TIMERn_CC1_CCV. These
bits are only used in output compare/pwm mode and are cleared when CCMODE is written to 0b00 (Off).
Value Description
0 TIMERn_CC1_CCVB does not contain valid data
1 TIMERn_CC1_CCVB contains valid data which will be written to TIMERn_CC1_CCV on the next update event
8 CCVBV0 0 R CC0 CCVB Valid
This field indicates that the TIMERn_CC0_CCVB registers contain data which have not been written to TIMERn_CC0_CCV. These
bits are only used in output compare/pwm mode and are cleared when CCMODE is written to 0b00 (Off).
Value Description
0 TIMERn_CC0_CCVB does not contain valid data
1 TIMERn_CC0_CCVB contains valid data which will be written to TIMERn_CC0_CCV on the next update event
7:3 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
2 TOPBV 0 R TOPB Valid
This indicates that TIMERn_TOPB contains valid data that has not been written to TIMERn_TOP. This bit is also cleared when
TIMERn_TOP is written.
Value Description
0 TIMERn_TOPB does not contain valid data
1 TIMERn_TOPB contains valid data which will be written to TIMERn_TOP on the next update event
1 DIR 0 R Direction
Indicates count direction.
Value Mode Description
