The A/D Converter is controlled by the following registers:
• A/D Converter mode registers 0, 1, 2 (ADA0M0, ADA0M1, ADA0M2)
• A/D Converter channel specification register 0 (ADA0S)
• Power-fail compare mode register (ADA0PFM)
The following registers are also used:
• A/D conversion result register n (ADCR0n)
• A/D conversion result register nH (ADCR0Hn)
• Power-fail compare threshold value register (ADA0PFT)
ADA0M0 - ADC mode register 0
The ADA0M0 register is an 8-bit register that specifies the operation mode and
controls conversion operations.
This register can be read orwritten in 8-bit or 1-bit units. However, bit 0 is read-
only.
Reset input clears this register to 00H.
