3.4.1 External Pins
Each HSCMP has up to eight external analog input pins and one external output pin.
Each input pin can accept an input voltage that varies across the full operating voltage
range of the DSC.
Consult the data sheet to determine what functions are shared with analog inputs. As
shown in the block diagram, the Pn pins are connected to the comparator non-inverting
input. Mn pins are connected to the inverting input of the comparator.
Freescale Semiconductor
• The Window Control block is completely bypassed when WE = 0.
• If WE = 1, the comparator output is sampled on every peripheral clock when
• The Filter block is bypassed when not in use.
• The Filter block acts as a simple sampler if bypass_Filter_Block && FILTER_CNT
• The Filter block filters based on multiple samples when bypass_Filter_Block &&
• If enabled, the Filter block incurs up to 1 IP Bus additional latency penalty on COUT
• WE and SE are mutually exclusive.
WINDOW = 1 to generate COUTA. Sampling does not occur when WINDOW = 0.
= 0x1.
FILTER_CNT > 0x1:
because COUT (which is crossing clock domain boundaries) must be resynchronized
to the peripheral clock.
• If SE = 1, the external SAMPLE input is used as sampling clock.
• IF SE = 0, the divided peripheral clock is used as sampling clock.
