16.8.1 Interrupt Enable Clear
This register allows the user to disable an interrupt without doing a read-modify-write operation. Changes in this register
will also be reflected in the Interrupt Enable Set register (INTENSET).
Name: INTENCLR
Offset: 0x00
Reset: 0x00000000
Property: Write-Protected
z Bits 31:18 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to
zero when this register is written. These bits will always return zero when read.
z Bit 17 – DPLLLTO: DPLL Lock Timeout Interrupt Enable
0: The DPLL Lock Timeout interrupt is disabled.
1: The DPLL Lock Timeout interrupt is enabled, and an interrupt request will be generated when the DPLL Lock
Timeout Interrupt flag is set.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the DPLL Lock Timeout Interrupt Enable bit, which disables the DPLL Lock Time-
out interrupt.
z Bit 16 – DPLLLCKF: DPLL Lock Fall Interrupt Enable
0: The DPLL Lock Fall interrupt is disabled.
1: The DPLL Lock Fall interrupt is enabled, and an interrupt request will be generated when the DPLL Lock Fall
Interrupt flag is set.
