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 (

) 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 (

) frequency is 20 MHz. When external clock

t2 is specified, the system clock (

) 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 (
