Figure 2. Mode Switching Waveforms
The X2 bit in the CKCON register (See Table 3.) allows to switch from 12 clock cycles
per instruction to 6 clock cycles and vice versa. At reset, the standard speed is activated
(STD mode). Setting this bit activates the X2 feature (X2 mode).
Note:
In order to prevent any incorrect operation while operating in X2 mode, user must be
aware that all peripherals using clock frequency as time reference (UART, timers) will
have their time reference divided by two. For example a free running timer generating an
interrupt every 20 ms will then generate an interrupt every 10 ms. UART with 4800 baud
rate will have 9600 baud rate.
