To turn certain bits on, the bitwise OR operation can be used, following the principle that Y OR 1 = 1 and Y OR 0 = Y. Therefore, to make sure a bit is on, OR can be used with a 1. To leave a bit unchanged, OR is used with a 0. Example: Masking on the higher nibble (bits 4, 5, 6, 7) while leaving the lower nibble (bits 0, 1, 2, 3) unchanged. Web21 de abr. de 2011 · 6.

Web13 de mar. de 2024 · If a GPIO interrupt is enabled, active, and masked, unmasking this interrupt causes the GPIO controller device to signal an interrupt request to the processor. A GPIO interrupt mask bit has no effect while the GPIO interrupt is disabled. The CLIENT_EnableInterrupt callback function sets the mask bit for the interrupt to zero; … Web9 de mar. de 2024 · 5 yields: x = 0101.
