If the WDSC[4:3] IDLEMODE bit field sets smart-idle wakeup-capable mode (= 0 × 3), the timer evaluates its internal capability to have the interface clock switched off. When there is no more internal activity (no pending interrupt sources: match, overflow, or timer capture events), the idle acknowledge signal is asserted and the timer enters into sleep mode, ready to issue a wake-up request. This wake-up request is sent only if the WIRQWAKEEN[0] OVF_WK_ENA and/or the WIRQWAKEEN[1] DLY_WK_ENA bits enable the overflow and/or the delay wake-up capability.
