Register Name:
Access Type:
Reset Value:
• OSC32K_RC_EN: Enable internal RC oscillator
0: No effect.
1: Enables the internal RC oscillator [enabled out of reset indicating system starts off of RC]
• OSC32K_XT_EN: Enable external crystal oscillator
0: No effect.
1: Enables the external crystal oscillator
• OSC32K_SEL: Slow clock source select
0: Selects internal RC as source of slow clock
1: Selects external crystal and source of slow
NOTE: After setting OSC32K_XT_EN bit, wait till 1.2s of on chip slow clock timing before setting OSC32K_SEL bit.
