TM4C1237E6PM: Voltage level mismatch

Part Number:TM4C1237E6PM

Hi community,

Please help me to find out the answer for the below queries

1)IO sink current

I have connected 2# LED Cathode through current limiting resistor  (150E) to PE1 and PE5 of TM4C1237E6PM. The LED Forward Current is 30mA .

Whether PE port has the capability to sink the 8mA current ? How it will be configured ?

2)VI & VH levels

I am facing TM4C MCU IO input and output voltage level mismatch with SPI Flash, RF SOC's. Please refer the below figure.

Here VOH of TM4C is not matching with VIH of SPI flash & CC1352. How this issue will be taken care ?

VIH(Min) of TM4C is not matching with VOH(min) of SOC2.

All four chip set supply voltage is 3.3V

Thanks & regards,

Divya
