14.4 Registers
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 (ADA0CRn)
• A/D conversion result register nH (ADA0CRnH)
• Power-fail compare threshold value register (ADA0PFT)
(1) A/D converter mode register 0 (ADA0M0)
The ADA0M0 register is an 8-bit register that specifies the operation mode and controls conversion.
This register can be read or written in 8-bit or 1-bit units. However, the ADA0EF bit is read-only.
Reset sets this register to 00H.
Caution Accessing the ADA0M0 register is prohibited in the following statuses. If a wait cycle is
ADA0M0
generated, it can be cleared only by a reset. For details, see 4.4.9 (1) Accessing special on-
chip peripheral I/O registers.
• When the CPU operates on the subclock and main clock oscillation is stopped
• When the CPU operates on the internal oscillator clock
After reset: 00H
