/(2) Anytime write and batch write
The TPnCCR0 and TPnCCR1 registers can be written even while TMPn is operating (that is, while the
TPnCTL0.TPnCE bit is 1), but the way the CCR0 and CCR1 buffer registers are written differs depending on
the mode. The two writing methods are anytime write and batch write.
(a) Anytime write
This writing method is used to transfer data from the TPnCCR0 and TPnCCR1 registers to the CCR0 and
CCR1 buffer registers any time while TMPn is operating.
Note The 16-bit counter is only cleared when its value matches the value of the CCR0 buffer
Remarks 1. The flowchart applies to the case when TMPn is being used as an interval
Timer operation
• 16-bit counter value matches value
• 16-bit counter value matches value
• 16-bit counter cleared and starts
• Set value to TPnCCRa register
• Enable timer
→ New value transferred to CCRa
(TPnCE bit = 1)
