RST — Module Reset Bit
When set, this bit causes all registers and activity in the module to
assume the same state as out of power-on reset (except for ADPU bit
in ATDCTL2, which remains set, allowing the ATD module to remain
enabled).
TSTOUT — Multiplex Output of TST[3:0] (Factory Use)
TST[3:0] — Test Bits 3 to 0 (Reserved)
Selects one of 16 reserved factory testing modes

PADx[7:0] — Port AD Data Input Bits
After reset these bits reflect the state of the input pins.
May be used for general-purpose digital input. When the software
reads PORTADx, it obtains the digital levels that appear on the
corresponding port AD pins. Pins with signals not meeting V_IL or V_IH
specifications will have an indeterminate value. Writes to this register
have no meaning at any time.
