Product data sheet
6.3.2 Clock control register (CKCON)
6.4 ALE control
By default, the device runs at twelve clocks per machine cycle. The device may be run in 6
clock per machine cycle mode by programming of either a non-volatile bit (FX2) or an SFR
bit
6-clock mode and the X2 SFR bit has no effect. If the FX2 bit is erased, then the clock
mode is controlled by the X2 SFR bit.
