OSCX Oscillation OSCX has two clock oscillators. The software options select the Ceramic/Crystal or RC as the CPU's sub clock. If the OSCX is not used, it must be selected as a ceramic resonator and the OSCXI must be connected to GND. OSCX Ceramic/Crystal Oscillator Type 47P-100 P OSCXI OSCX RC Oscillator Type 455kHz Ceramic OSCXO 47P-100 P CHIP ROSCX OSCXI 102 OSCXO CHIP et4U.com 4.4. Control of Oscillator The oscillator control register configuration is shown as follows: Address $14 Bit3 OXS Bit2 Bit1 Bit0 - DataSOhXeMet4U.com OXON OXON: OSCX oscillation on/off. 0: Turn-off OSCX oscillation OXM: switching system oscillator. 0: select OSC as system oscillator OXS: OSCX oscillator type selection 0: OSCX set as Ceramic Resonator/Crystal Oscillator 1: Turn-on OSCX oscillation 1: select OSCX as system oscillator 1: OSCX set as RC oscillator 4.5. Programming Notes It takes at least 5 ms for the OSCX oscillation circuit to turn on until the oscillation stabilizes. When switching the CPU system clock from OSC to OSCX, the user must wait a minimum of 5ms since the OSCX oscillation is running. However, the start time varies with respect to oscillator characteristics and the condition of use. Thus the wait time depends on the application. When switching from OSCX to OSC, the user should switch clock first then turn off OSCX. If switching from OSCX to OSC and turning off OSCX in one instruction, the OSCX turn off control will be delayed for one instruction cycle automatically to prevent CPU operation error. Following is the timing of system clock switching.
