Mode Switching Waveforms
The X2 bit in the CKCON0 register (see Table 5) allows to switch from 12 clock periods
per instruction to 6 clock periods and vice versa. At reset, the speed is set according to
X2 bit of Hardware Config Byte (HCB). By default, Standard mode is activated. Setting
the X2 bit activates the X2 feature (X2 mode).
The T0X2, T1X2, T2X2, UARTX2, PCAX2 and WDX2 bits in the CKCON0 register
(Table 5) allow to switch from standard peripheral speed (12 clock periods per periph-
eral clock cycle) to fast peripheral speed (6 clock periods per peripheral clock cycle).
These bits are active only in X2 mode.
