LPITx_TCTRLn field descriptions (continued)
Field Description
When set, the LPIT timer will reload when a rising edge is detected on the selected trigger input. The
trigger input is ignored if the LPIT is disabled during debug mode or DOZE mode (DOZE_EN or DBGEN =
0)
0 Timer will not reload on selected trigger
1 Timer will reload on selected trigger
17
TSOI
Timer Stop On Interrupt
This bit controls whether the channel timer will stop after it times out and when it can restart (when TSOT
= 0). If TSOT = 1, then the timer will stop on timeout and will restart after a rising edge on the selected
trigger is detected. If TSOT = 0, then this bit controls when the timer restarts.
0 Timer does not stop after timeout
1 Timer will stop after timeout and will restart after rising edge on the T_EN bit is detected (i.e. timer
channel is disabled and then enabled)
16
TSOT
Timer Start On Trigger
This bit controls when the timer starts decrementing.
0 Timer starts to decrement immediately based on restart condition (controlled by TSOI bit)
1 Timer starts to decrement when rising edge on selected trigger is detected
15–4
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
3–2
MODE
Timer Operation Mode
Configures the Channel Timer Mode of Operation. The mode bits control how the timer decrements. See
Functional Description for more details.
00 32-bit Periodic Counter
01 Dual 16-bit Periodic Counter
10 32-bit Trigger Accumulator
11 32-bit Trigger Input Capture
1
CHAIN
Chain Channel
When enabled, timer channel will decrement when channel N-1 trigger asserts. Channel 0 cannot be
chained.
0 Channel Chaining is disabled. Channel Timer runs independently.
1 Channel Chaining is enabled. Timer decrements on previous channel's timeout
0
T_EN
Timer Enable
Enables or disables the Timer Channel
0 Timer Channel is disabled
1 Timer Channel is enabled
