The A/D converter uses the following seven types of registers.
(1) Peripheral enable register 0 (PER0)
(2) A/D converter mode register (ADM)
(3) 10-bit A/D conversion result register (ADCR)
(4) 8-bit A/D conversion result register (ADCRH)
(5) Analog input channel specification register (ADS)
(6) A/D port configuration register (ADPC)
(7) Port mode registers 2 (PM2)
Bit 5 of this register is used to enable or stop operation of the A/D converter. The default value of this bit is set
to stop operation of the A/D converter.
This register is used to set conversion time of an input analog signal to be converted, and to start or stop the
conversion operation.
Each time A/D conversion has been completed, the conversion result is loaded from the successive
approximation register to this register that holds the A/D conversion result at the higher 10 bits (the lower 6 bits
are fixed to 0).
Each time A/D conversion has been completed, the conversion result is loaded from the successive
approximation register to this register that stores the A/D conversion result in the higher 8 bits.
This register is used to specify a port that inputs an analog voltage to be converted.
This register is used to set the ANI0/P20 to ANI7/P27 pins in the analog input mode of the A/D converter or
digital I/O mode of the ports.
These registers are used to set the ANI0/P20 to ANI7/P27 pins in the input or output mode.
