Technical information

5
In the E6000, the clock can be selected by using the Configuration window or the Clock
command.

8 8 MHz internal clock
10 10 MHz internal clock
12 12.5 MHz internal clock Default
16 16 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 (f
ff
f) frequency is the same clock
frequency input to the XTAL and EXTAL when external clock
t is specified. For example, when a 20-MHz crystal
oscillator is connected to the XTAL and EXTAL of the user
system, the system clock (f
ff
f) frequency is 20 MHz. When
external clock t2 is specified, the system clock (f
ff
f) 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 (f
ff
f).
