WATCHDOG TIMER (Cont’d)
8.1.7 Register Description
WATCHDOG REGISTER (WDGR)
Address: 0D8h - Read/Write
Reset Value: 1111 1110 (FEh)
7
T0
T1
T2
T3
T4
Bits 7:2 = T[5:0] Downcounter bits
Caution: These bits are reversed and shifted with
respect to the physical counter: bit-7 (T0) is the
LSB of the Watchdog downcounter and bit-2 (T5)
is the MSB.
Bit 1 = SR: Software Reset bit
Software can generate a reset by clearing this bit
while the C bit is set. When C = 0 (Watchdog de-
activated) the SR bit is the MSB of the 7-bit timer.
0: Generate (write)
1: No software reset generated, MSB of 7-bit timer
ST6208C/ST6209C/ST6210C/ST6220C
Bit 0 = C Watchdog Control bit.
If the hardware option is selected (WDACT bit in
Option byte), this bit is forced high and cannot be
changed by the user (the Watchdog is always ac-
tive). When the software option is selected
(WDACT bit in Option byte), the Watchdog func-
0
tion is activated by setting the C bit, and cannot
then be deactivated (except by resetting the
T5
SR
C
MCU).
When C is kept cleared the counter can be used
as a 7-bit timer.
0: Watchdog deactivated
1: Watchdog activated
