R5 shutter speed in manual mode slowest 1/2 second

[Tim87]

Hi. I just purchased a new Canon EOS R5 mirrorless camera after using the 5D Mark IV the last few years. The slowest shutter speed for stills is 1/2 second in manual mode. 
I have not tried other modes as I always use manual. 
Is there a reason why or a setting that needs to be changed? # R5

My apologies, I was a bit hasty in replying and now checked the manual page referred to. I realise that Ricky was talking about the shutter limits that apply to P and Av modes when using auto ISO. I mistakenly thought his reference was to the shutter speed limits that are set in custom functions, as those do apply in all of the creative modes as I mentioned.

Sorry, I had searched the User Manual simply on "minimum" and found that one page that mentioned "Manual", so assumed M mode.
