• OSCM2, OSCM1, OSCM0 (bits 6, 3, 2)
Address: 0F002H
Access: R/W
Access size: 8/16 bits
Initial value: 33H
FCON0 is a special function register (SFR) to control the high-speed clock generation circuit and to select system
clock.
[Description of Bits]
− When switching the high-speed oscillation mode, please first switch back to low speed clock before switching to
Initial value
•
The SYSC1 and SYSC0 bits are used to select the frequency of the high-speed clock (HSCLK) used for system
clock and periphera1 circuits (including high-speed time base counter). OSCLK, 1/2OSCLK, 1/4OSCLK, or
1/8OSCLK can be selected. The maximum operating frequency guaranteed for the system clock (SYSCLK) of this
LSI is 4.2 MHz.
At system reset, 1/8OSCLK is selected.
The OSCM2, OSCM1 and OSCM0 bits are used to select the mode of the high-speed clock generation circuit.
500kHz RC oscillation mode, crystal/ceramic oscillation mode, PLL oscillation mode, external clock input mode, or
2MHz RC oscillation mode can be selected.
The setting of OSCM1 and OSCM0 can be changed only when high-speed oscillation is being stopped (ENOSC bit
of FCON1 is “0”). At system reset, RC oscillation mode is selected.
other high-speed clock (set the ENOSC bit and SYSCLK bit of FCON1 to “0”).
