has no effect).
Cleared to select 6 clock periods per peripheral clock cycle.
Set to select 12 clock periods per peripheral clock cycle.
5PCAX2
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.
4SIX2
Enhanced UART Clock (Mode 0 and 2)
(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.
3T2X2
Timer 2 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.
2T1X2
Timer 1 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.
1T0X2
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.
0X2
CPU Clock
Cleared to select 12 clock periods per machine cycle (STD, X1 mode) for CPU
and all the peripherals. Set to select 6 clock 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.
