Table 270, Table 271, Table 272 and Table 273 are listing the sources connected to the
tim_ti[1..4] input multiplexers.
tim_ker_ck Input
Timer kernel clock. This clock must be
synchronous with tim_pclk (derived from the
same source). The clock ratio
tim_ker_ck/tim_pclk must be an integer:1, 2,
3,..., 8 (maximum value).
tim_it Output
Global Timer interrupt, gathering
capture/compare, update, break trigger and
commutation requests.
tim_cc1_dma
tim_cc2_dma
tim_cc3_dma
tim_cc4_dma
Output Timer capture / compare 1..4 dma requests.
tim_upd_dma Output Timer update dma request.
tim_trg_dma Output Timer trigger dma request.
tim_com_dma Output Timer commutation dma request.
