• Manufacturer Part Number: mpc82x54a
• Description: 8-bit Micro-controller
• Manufacturer: Megawin Technology

MEGAWIN
SFR: ADCTL (ADC Control register)
SFR: ADCV (ADC Result Register):
SFR: ADCVL (ADC Result Low):
ADCON :=
{SPEED1, SPEED0}:= Conversion speed selector
ADCS := ADC Start control
ADCI := ADC Interrupt flag
{CHS2, CHS1, CHS0} := Input Channel Selector
The {ADCV[7:0], ADCVL[1:0]} is the final result from the A/D conversion.

It will be set by the device after the device has finished a conversion, and
should be cleared by the user’s software.
A conversion takes 1080 clock cycles
A conversion takes 810 clock cycles
A conversion takes 540 clock cycles
A conversion takes 270 clock cycles
Set to start an A/D conversion. It will be automatically cleared by the device
Set P1.0 as the A/D channel input
Set P1.1 as the A/D channel input
Set P1.2 as the A/D channel input
Set P1.3 as the A/D channel input
Set P1.4 as the A/D channel input
Set P1.5 as the A/D channel input
Set P1.6 as the A/D channel input
Set P1.7 as the A/D channel input
after the device has finished the conversion.
When clear shut down the power of ADC block. When set turn on the power
of ADC block.
