OTHER EPROM OPTIONS
The DS87C550 has user-selectable options that must be set before beginning software execution. These
options use EPROM bits rather than SFRs.
The EPROM selectable options may be programmed as shown in Table 10. The Option Register sets or
reads these selections. The bits in the Option Register have the following function:
Bit 7 -4
Bit 3
Reserved. Program to a 1.
Watchdog POR default. Set to 1:
Watchdog reset function is disabled on power-up. Set to 0: Watchdog reset function is
enabled automatically.
Reserved. Program to a 1.
Bit 2-0
