Set the same value as 000C0H to 010C0H when the boot swap operation is used because 000C0H is
replaced by 010C0H.
The window open period is 100% when WDSTBYON = 0, regardless the value of WINDOW1 and
WINDOW0.
Set the same value as 000C1H to 010C1H when the boot swap operation is used because 000C1H is
replaced by 010C1H.
When 8 MHz or 20 MHz has been selected, the 8 MHz internal high-speed oscillator automatically starts
oscillating after reset release.
microcontroller, oscillation is started by setting bit 0 (DSCON) of the 20 MHz internal high-speed oscillation
control register (DSCCTL) to 1 with V
speed oscillator while the microcontroller operates.
When 1 MHz has been selected, the microcontroller operates on the 1 MHz internal high-speed oscillator
after reset release. The circuit cannot be changed to an 8 MHz or 20 MHz internal high-speed oscillator
while the microcontroller operates.
