13.3 Control Registers
552
A/D converter 2 is controlled by the following registers.
• A/D converter 2 control registers 0 to 3 (ADA2CTL0 to ADA2CTL3)
• A/D converter 2 status register (ADA2STR)
The following registers are also used.
• A/D2 conversion result registers 0 to 7 (ADA2CR0 to ADA2CR7)
• A/D2 conversion result registers 0H to 7H (ADA2CR0H to ADA2CR7H)
(1) A/D converter 2 control register 0 (ADA2CTL0)
Caution Do not set the analog power supply control bit (ADA2PON) and A/D conversion operation bit
The ADA2CTL0 register is an 8-bit register that controls the analog power supply and conversion operations.
This register can be read or written in 8-bit or 1-bit units. However, bits 6 and 7 are write-only in 1-bit units.
Reset sets this register to 00H.
(ADA2CE) to 1 at the same time. Set the ADA2CE bit to 1 at least 5
was set to 1. If the ADA2CE bit is set to 1 before the lapse of 5
but the accuracy of the result of the first conversion cannot be guaranteed.
