OPTION Register
When the OPTIONX bit in the FUSE word is cleared, bits
7 and 6 of the OPTION register function as described
below.
When the OPTIONX bit is set, bits 7 and 6 of the
OPTION register read as ‘1’s.
RTW
RTCC/W register selection:
0 = Register 01h addresses W
1 = Register 01h addresses RTCC
RTE_IE
RTCC edge interrupt enable:
0 = RTCC roll-over interrupt is enabled
1 = RTCC roll-over interrupt is disabled
RTS
RTCC increment select:
0 = RTCC increments on internal instruction
cycle
1 = RTCC increments upon transition on
RTCC pin
RTE_ES
RTCC edge select:
0 = RTCC increments on low-to-high transi-
tions
1 = RTCC increments on high-to-low transi-
tions
PSA
Prescaler Assignment:
0 = Prescaler is assigned to RTCC, with di-
vide rate determined by PS0-PS2 bits
1 = Prescaler is assigned to WDT, and divide
rate on RTCC is 1:1
PS2-PS0
Prescaler divider (see Table 4-2)
Upon reset, all bits in the OPTION register are set to 1.
