Function Documentation

void Cy_SysClk_PiloEnable ( void )

Enables the PILO.

Note: This function blocks for 1 millisecond between enabling the PILO and releasing the PILO reset.

Function Usage: /* Scenario: PILO needs to source the LFCLK. All peripherals clocked by

the LFCLK are disabled and the Watchdog timer (WDT) is unlocked. */

/* Enable the PILO. Note: Blocks for 1 millisecond. */

Cy_SysClk_PiloEnable();

/* Set the LFCLK source to the PILO */

Cy_SysClk_ClkLfSetSource(CY_SYSCLK_CLKLF_IN_PILO);

CY_SYSCLK_CLKLF_IN_PILO
@ CY_SYSCLK_CLKLF_IN_PILO
clkLf is sourced by the precision low speed oscillator (PILO)
