T0X12:
=
T0
clock source selector
0:=
(default)
Set the frequency of the clock source for
T0
as the oscillator frequency divided-by-12.
It will compatible to the traditional 80C51 MCU.
1:=
Set the frequency of the clock source for
T0
as the oscillator frequency.
It will drive the
T0
faster than a traditional 80C51 MCU.
T1X12:
=
T1
clock source selector
0:=
(default)
Set the frequency of the clock source for
T1
as the oscillator frequency divided-by-12.
It will compatible to the traditional 80C51 MCU.
1:=
Set the frequency of the clock source for
T1
as the oscillator frequency.
It will drive the
T1
faster than a traditional 80C51 MCU.
URM0X6:
= Baud rate selector of UART while it is working under Mode-0
0:=
(default)
Set the baud rate of the UART functional block as oscillator frequency divided-by-12.
It will compatible to the traditional 80C51 MCU.
1:=
Set the baud rate of the UART functional block as oscillator frequency divided-by-2.
It will transmit/receive data faster than a traditional 80C51 MCU.
EADCI:
= Enable/Disable interrupt from A/D converter
0:=
(default)
Inhibit the ADC functional block to generate interrupt to the MCU
1:=
Enable the ADC functional block to generate interrupt to the MCU
ESPI:
= Enable/Disable interrupt from Serial Peripheral Interface (SPI)
0:=
(default)
Inhibit the SPI functional block to generate interrupt to the MCU
1:=
Enable the SPI functional block to generate interrupt to the MCU
ENLVFI:
= Enable/Disable interrupt from low-voltage sensor
0:=
(default)
Inhibit the low-voltage sensor functional block to generate interrupt to the MCU
1:=
Enable the low-voltage sensor functional block to generate interrupt to the MCU
