X2 is low, this bit has no effect)
Cleared to select 6 clock periods per peripheral clock cycle.
Set to select 12 clock periods per peripheral clock cycle.
6
WDX2
Watchdog clock (This control bit is validated when the CPU clock X2 is set;
when X2 is low, this bit has no effect)
Cleared to select 6 clock periods per peripheral clock cycle.
Set to select 12 clock periods per peripheral clock cycle.
5
PCAX2
Programmable Counter Array clock (This control bit is validated when the
CPU clock X2 is set; when X2 is low, this bit has no effect)
Cleared to select 6 clock periods per peripheral clock cycle.
Set to select 12 clock periods per peripheral clock cycle.
4
SIX2

X2 is low, this bit has no effect)
Cleared to select 6 clock periods per peripheral clock cycle.
Set to select 12 clock periods per peripheral clock cycle.
1
T0X2
Timer0 clock (This control bit is validated when the CPU clock X2 is set; when
X2 is low, this bit has no effect)
Cleared to select 6 clock periods per peripheral clock cycle.
Set to select 12 clock periods per peripheral clock cycle.
0
X2
CPU clock
Cleared to select 12 clock periods per machine cycle (STD mode) for CPU and
all the peripherals.
Set to select 6clock periods per machine cycle (X2 mode) and to enable the
individual peripherals "X2" bits.
Programmed by hardware after Power-up regarding Hardware Security Byte
(HSB), Default setting, X2 is cleared.
