5.3.1.2
Timer 1 Control Register 2 (T1C2)
Bit 3 = MSB, Bit 0 = LSB
5.3.1.3
Watchdog Control Register (WDC)
Bit 3 = MSB, Bit 0 = LSB
Both these bits control the time interval for the watchdog reset.
Address: ’7’hex - Subaddress: ’9’hex
Bit 3
Bit 2
Bit 1
Bit 0
T1C2
T1BP
T1CS
T1IM
Reset value: x111b
T1BP
Timer 1 SUBCL ByPassed
T1BP = 1, TIOUT = T1MUX
T1BP = 0, T1OUT = SUBCL
T1CS
Timer 1 input Clock Select
T1CS = 1, CL1 = SUBCL (see Figure 5-8 on page 33)
T1CS = 0, CL1 = SYSCL (see Figure 5-8 on page 33)
T1IM
Timer 1 Interrupt Mask
T1IM = 1, disables Timer 1 interrupt
T1IM = 0, enables Timer 1 interrupt
Address: ’7’hex - Subaddress: ’A’hex
Bit 3
Bit 2
Bit 1
Bit 0
WDC
WDL
WDR
WDT1
WDT0
Reset value: 1111b
WDL
WatchDog Lock mode
WDL = 1, the watchdog can be enabled and disabled by using the WDR-bit
WDL = 0, the watchdog is enabled and locked. In this mode the WDR-bit has no
effect. After the WDL-bit is cleared, the watchdog is active until a system
reset or power-on reset occurs.
WDR
WatchDog Run and stop mode
WDR = 1, the watchdog is stopped/disabled
WDR = 0, the watchdog is active/enabled
WDT1
WatchDog Time 1
WDT0
WatchDog Time 0
