C

uint32_t GPIO_PortLatchRead ( GPIO_PORT port )

Summary

Read the latched value on all the I/O lines of the selected port.

Description

This function reads the latched data values on all the I/O lines of the selected port. Bit values returned in each position indicate corresponding pin levels.

• 1 - Pin is high.

• 0 - Pin is low.

Precondition

None.

Parameters

Returns

Returns the latch register value of the specified I/O port

Example

uint32_t value;
value = GPIO_PortLatchRead(GPIO_PORT_C);

Remarks

If the port has less than 32-bits, unimplemented pins will read as low (0). Implemented pins are Right aligned in the 32-bit return value.
