Section 13 8-Bit Timer (TMR)
Table 13.2 Clock Input to TCNT and Count Condition
Legend:
Note: * If the TMR_0 clock input is set as the TCNT_1 overflow signal and the TMR_1 clock input is set as

the TCNT_0 compare-match signal simultaneously, a count-up clock cannot be generated.
Simultaneous setting of this condition should therefore be avoided.
