What are TIMx TIx[1..15] input signals?

GPope.1

TIM1 section figures 55 and 79 in G0 reference manual RM0454 Rev2 refer to TI2[1..15] as selectable sources for TI2 signal (see also TI2SEL register bits). It appears that TI2[0] is the TIM1_CH2 pin, but what are the sources for the TI2[1..15] signals? What are they connected to? Is this explained somewhere in the reference manual?

Thanks.

It sounds like they're not connected to anything, but could be in a future chip revision. RM says those values other than TI2[0] are reserved.

These chips are designed by connecting together individual blocks (i.e. processor, clocks, memories, busmatrix, peripherals, GPIO...)

ST, in a fair attempt to illustrate better the internal interconnections, since the, H7 family started to use names of internal signals interconnecting these blocks, throughout the RM. Theyb are usually in lowercase, but there are exceptions. Often, they are described in the Interconnections chapter in RM.

As TDK said, these signals are not always connected in a given particular chip, they may be used in other, maybe bigger, chips, but are mentioned because they form part of the given peripheral/module.

Think of a software library's API as an analogy - not in all uses of a particular library are all available functions used...
