(2) Anytime write and batch write
The TQ0CCR0 to TQ0CCR3 registers can be written even while TMQ0 is operating (that is, while the
TQ0CTL0.TQ0CE bit is 1), but the way the CCR0 to CCR3 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 TQ0CCR0 to TQ0CCR3 registers to the CCR0 to
CCR3 buffer registers any time while TMQ0 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 TMQ0 is being used as an interval
Rewrite TQ0CCRm register
→ New value transferred to CCRm
Timer operation
• 16-bit counter value matches value
• 16-bit counter value matches value
• 16-bit counter cleared and starts
• Set value to TQ0CCRm register
• Enable timer
