ADC0TH
0xFFFF0550
0x0000
Read/Write
This 16-bit MMR sets the threshold against which the absolute value of the I-ADC conversion result is compared. In
Unipolar mode ADC0TH [15:0] are compared and in 2’s complement mode ADC0TH[14:0] are compared.
ADC0TCL
0xFFFF0554
0x01
Read/Write
This 8-bit MMR determines how many cumulative (given values below the threshold will decrement or reset the count
to 0) I-ADC conversion result readings above ADC0TH must occur before the I-ADC Comparator Threshold bit is set
in the ADCSTA MMR generating an ADC interrupt. The I-ADC Comparator Threshold bit is asserted as soon as the
ADC0THV=ADC0TCL.
ADC0THV
0xFFFF0558
0x00
Read Only
This 8-bit MMR is incremented every time the absolute value of an I-ADC conversion result |I| >= ADC0TH. This
register is decremented or reset to 0 every time the absolute value of an I-ADC conversion result |I| < ADC0TH. The
configuration of this function is enabled via the Current Channel ADC Comparator bits in the ADCCFG MMR.
ADC0ACC
0xFFFF055C
0x00000000
Read Only
This 32-bit MMR holds the current accumulator value. The I-ADC READY bit in the ADCSTA MMR should be used
to determine when it is safe to read this MMR. The MMR value is reset to 0 by disabling the accumulator in the
ADCCFG MMR or reconfiguring the Current Channel ADC.
