See Table 1. 20 FSEL_C 1 0 FSEL_B 0 0 FSEL_A Byte 10: Control Register 10 Bit @Pup Name Description 7 0 Recovery_Frequency This bit allows selection of the frequency setting that the clock will be restored to once the system is rebooted 0: Use HW settings 1: Recovery N[8:0] 6 0 Timer_SEL Timer_SEL selects the WD reset function at SRESET pin when WD time out. 0 = Reset and Reload Recovery_Frequency 1 = Only Reset 5 1 Time_Scale Time_Scale allows selection of WD time scale 0 = 294 ms 1 = 2.34 s 4 0 WD_Alarm WD_Alarm is set to “1” when the Watchdog times out. It is reset to “0” when the system clears the WD_TIMER time stamp. 3 0 WD_TIMER2 Watchdog timer time stamp selection 000: Reserved (test mode) 001: 1 * Time_Scale 010: 2 * Time_Scale 011: 3 * Time_Scale 100: 4 * Time_Scale 101: 5 * Time_Scale 110: 6 * Time_Scale 111: 7 * Time_Scale 20 WD_TIMER1 10 WD_TIMER0 0 0 WD_EN Watchdog timer enable, when the bit is asserted, Watchdog timer is triggered and time stamp of WD_Timer is loaded 0 = Disable, 1 = Enable Byte 11: Control Register 11 Bit @Pup Name Description 7 0 CPU_DAF_N7 If Prog_CPU_EN is set, the values programmed in CPU_DAF_N[8:0] and CPU_DAF_M[6:0] will be used to determine the CPU output frequency. The setting of FS_Override bit determines the frequency ratio for CPU and other output clocks. When it is cleared, the same frequency ratio stated in the Latched FS[E:A] register will be used. When it is set, the frequency ratio stated in the FSEL[3:0] register will be used. 6 0 CPU_DAF_N6 5 0 CPU_DAF_N5 4 0 CPU_DAF_N4 3 0 CPU_DAF_N3 2 0 CPU_DAF_N2 1 0 CPU_DAF_N1 0 0 CPU_DAF_N0 |
