15.4.3 Option
The OPTION register is a run-time writable register used to configure the RTCC and the Watchdog
Timer. The size of this register is affected by the OPTIONX device setting.
15.4.4 Fuse Registers
The Fuse registers are accessible only at program time. The SX-Key Development System Software
provides a convenient interface that is easy to use to customize the SX. You may use the predefined

When OPTION Extend = 0, bits 7 and 6 are implemented.
When OPTION Extend = 1, bits 7 and 6 read as ‘1’s.
RTW - If = 0, register $01 is W
RTI
RTS - If = 0, RTCC increments on internal instruction cycle
RTE - If = 0, RTCC increments on low-to-high transition
PSA - If = 0, prescaler is assigned to RTCC, divide rate determined by PS0-PS2 bits
- If = 0, RTCC roll-over interrupt is enabled
If = 1, register $01 is RTCC
If = 1, RTCC roll-over interrupt is disabled
If = 1, RTCC increments on transition of RTCC pin
If = 1, RTCC increments on high-to-low transition
If = 1, prescaler is assigned to WDT, and divide rate on RTCC is 1:1
