TPMx_CnSC field descriptions
Field
Description
31–8
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
7
CHF
Channel Flag
Set by hardware when an event occurs on the channel. CHF is cleared by writing a 1 to the CHF bit.
Writing a 0 to CHF has no effect.
If another event occurs between the CHF sets and the write operation, the write operation has no effect;
therefore, CHF remains set indicating another event has occurred. In this case a CHF interrupt request is
not lost due to the delay in clearing the previous CHF.
0
No channel event has occurred.
1
A channel event has occurred.
6
CHIE
Channel Interrupt Enable
Enables channel interrupts.
0
Disable channel interrupts.
1
Enable channel interrupts.
5
MSB
Channel Mode Select
Used for further selections in the channel logic. Its functionality is dependent on the channel mode. When
a channel is disabled, this bit will not change state until acknowledged in the TPM counter clock domain.
4
MSA
Channel Mode Select
Used for further selections in the channel logic. Its functionality is dependent on the channel mode. When
a channel is disabled, this bit will not change state until acknowledged in the TPM counter clock domain.
3
ELSB
Edge or Level Select
The functionality of ELSB and ELSA depends on the channel mode. When a channel is disabled, this bit
will not change state until acknowledged in the TPM counter clock domain.
2
ELSA
Edge or Level Select
The functionality of ELSB and ELSA depends on the channel mode. When a channel is disabled, this bit
will not change state until acknowledged in the TPM counter clock domain.
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
27.3.5 Channel (n) Value (TPMx_CnV)
These registers contain the captured TPM counter value for the input modes or the match
value for the output modes.
In input capture mode, any write to a CnV register is ignored.
