Question 2GPIO Port 2 pin mode is set by which register?1 pointP1DIRP2OUTP1SELx P2SELxP1IN

Break Down the Problem

1. Identify what a GPIO port is and its functionality.
2. Determine which register is associated with setting the pin mode for GPIO Port 2.

Relevant Concepts

1. General Purpose Input/Output (GPIO) pins can be configured for multiple functions depending on the register used.
2. The registers mentioned in the options typically control either direction, output, or selection of functions for each GPIO pin.

Analysis and Detail

1. P1DIR: This register sets the direction for Port 1, so it's not relevant for Port 2.
2. P2OUT: This register controls the output for Port 2 but does not set the pin mode.
3. P1SELx: This register is for selecting functions for Port 1 only.
4. P2SELx: This register is responsible for selecting the alternate functions for Port 2.
5. P1IN: This register reads the input of Port 1, not related to the pin mode of Port 2.

Verify and Summarize

Based on the functions of the registers, P2SELx is the correct register for setting the pin mode of GPIO Port 2.

Final Answer

P2SELx is the register that sets the pin mode for GPIO Port 2.
