1. DLY can be written only once in the first 64 cycles out of reset in normal modes or at any
ADPU — A/D Power-up
CSEL — Clock Select
All bits in this register can be read or written except bit 7, which is a
read-only status indicator, and bit 6, which always reads as 0. Writing to
ADCTL initiates a conversion, aborting any conversion in progress.
