How many 32 bit timers does STM32H573 have? 2 or 4? Conflicting information in data sheet

Hello,

I'm refering to DS14121 Rev 1 of STM32H573xx. 

- "Figure 1. STM32H573xx block diagram" shows 4 32 bit timers (TIM2, TIM3, TIM4, TIM5)

- "Table 2. STM32H573xx features and peripheral counts" says there are only two.

Where can I find trustworthy information on the correct number?

Have a nice day,

F

What does "typically" mean? Is there any STM32H573 that has four 32 bit timers?

where are the missing 2 x 32 bit counters?

tim2 + 5 are 32 bit:

It is literally the first issue reported in the second sentence of the head post. But, of course, who could notice such a "hidden" text...
