LOCK=UNLOCKED, CLKSEL=IRC
Watchdog clock select register.
| CLKSEL | Selects source of WDT clock 0 (RESERVED): Reserved. 0 (IRC): IRC 1 (PCLK): Peripheral clock 2 (RTCOSC): RTC oscillator |
| RESERVED | Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined. |
| LOCK | If this bit is set to one writing to this register does not affect bit 0. The clock source can only be changed by first clearing this bit, then writing the new value of bit 0. 0 (UNLOCKED): This bit is set to 0 on any reset. It cannot be cleared by software. 1 (LOCKED): Software can set this bit to 1 at any time. Once WDLOCK is set, the bits of this register cannot be modified. |
