IO current sinking

Hi guys,


I am reading the datasheet of the MC9SH8QG4 and I see next data:


Maximum total IOH for all port pins | IOHT | — 60 mA

Maximum total IOL for all port pins IOLT — 60 mA


I want to power about 8 leds, and each one has a current consumptiom about 50mA. Can I power the leds directly with the microcontroller or shall I need to use transistors? I am not sure if the "maximum total IOL/H" is for one pin or all the pins of the microcontroller.
