Table 246, Table 247, Table 248 and Table 249 list the sources connected to the tim_ti[1..4]
input multiplexers.
tim_ocref_clr[7:0] Input
Timer tim_ocref_clr input bus. These inputs
can be used to clear the tim ocxref signals,
typically for hardware cycle-by-cycle
pulsewidth control.
tim_brk_cmp[7:1] Input Break input for internal signals
tim_brk2_cmp[7:1] Input Break2 input for internal signals
tim_sys_brk[n:0] Input
System break input. This input gathers the
MCU’s system level errors.
tim_pclk Input Timer APB clock
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,..., 16 (maximum value)
tim_cc_it Output Timer capture/compare interrupt
tim_upd_it Output Timer update event interrupt
tim_brk_terr_ierr_it Output
Timer break, break2, transition error and
index error interrupt
tim_trg_com_dir_idx_it Output
Timer trigger, commutation, direction and
index interrupt
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
