1.5 OPTION BYTE
The user has the option to select software watch-
dog or hardware watchdog (see description in the
Watchdog chapter). When programming EPROM
or OTP devices, this option is selected in a menu
by the user of the EPROM programmer before
burning the EPROM/OTP. The Option Byte is lo-
cated in a non-user map. No address has to be
specified. The Option Byte is at FFh after UV eras-
ure and must be properly programmed to set de-
sired options.
OPTBYTE
Bit 7:4 = Not used
Bit 3 = Reserved, must be cleared.
Bit 2 = Reserved, must be set on ST72T121N de-
vices and must be cleared on ST72T121J devices.
Bit 1 = Not used
Bit 0 =
WDG
Watchdog disable
0: The Watchdog is enabled after reset (Hardware
Watchdog).
