A/D data register-upper (ADRU: $02B)
Figure 69 A/D Data Register-Upper (ADRU)
Module standby register 2 (MSR2: $00E):
Writing 1 to bit 1 of module standby register 2 stops the supply of the system clock to the A/D module and
cuts the current (I
AD
) flowing in the ladder resistor.
Usage notes:
Use the SEM or SEMD instruction to write to the A/D start flag (ADSF).
Do not write to the ADSF during A/D conversion.
Data in the A/D data register is undetermined during A/D conversion.
