Technical information

In the E6000, the clock can be selected by using the Configuration window or the Clock
command.

8 8 MHz internal clock Default
10 10 MHz internal clock
18 18 MHz internal clock
20 20 MHz internal clock
25 25 MHz internal clock
t Target
t2 Target/2 Not supported by the actual MCU.
Use this clock only when the required clock
duty cannot be obtained.
NOTE
The system clock (φ) frequency is the same clock
frequency input to the XTAL and EXTAL when external clock
t is specified. For example, when a 18-MHz crystal oscillator
is connected to the XTAL and EXTAL of the user system, the
system clock (φ) frequency is 18 MHz. When external clock
t2 is specified, the system clock (φ) frequency is 1/2 of the
clock frequency input to the XTAL and EXTAL.
The frequency of the E6000 internal clock specified with
the HDI CLOCK command is applied to the system clock (φ).
