用語(terms)

Term	Description
CS	Chip select
DIO	Digital Input Output
ECU	Electric Control Unit
EOL	End Of Line Often used in the term ‘EOL Programming’ or ‘EOL Configuration’ ICU Input Capture Unit
MAL	Old name of Microcontroller Abstraction Layer (replaced by MCAL because ‘MAL’ is a French term meaning ‘bad’)
MCAL	Microcontroller Abstraction Layer
MCU	Microcontroller Unit
MMU	Memory Management Unit
Master	A device controlling other devices (slaves, see below)
Slave	A device being completely controlled by a master device
NMI	Non maskable interrupt
OS	Operating System
PLL	Phase Locked Loop
PWM	Pulse Width Modulation
RX	Reception (in the context of bus communication)
SPAL	The name of this working group
SFR	Special Function Register
RTE	Runtime environment
WP	Work Package
ADC	Analogue Digital Converter
FFT	Fast Fourier Transformer
STD	Standard
REQ	Requirement
UNINIT	Uninitialized (= not initialized)
HW Unit	Represents a microcontroller input electronic device that includes all parts necessary to perform an “analogue to digital conversion”.
ADC channel	Represents a logical ADC entity bound to one port pin. Multiple ADC entities can be mapped to the same port pin.
ADC channel group	A group of ADC channels linked to the same ADC hardware unit (e.g. one Sample&Hold and one A/D converter). The conversion of the whole group is triggered by one trigger source.
ADC result buffer	The user of the ADC Driver has to provide a buffer for every group. This buffer can hold multiple samples of the same channel group if streaming access mode is selected. If single access mode is selected one sample of each group channel is held in the buffer.
Trigger Source	Source event that starts a single conversion or a continuous series of conversions.
Conversion Mode	One-Shot: The conversion of an ADC channel group is performed once after a trigger and the result is written to the assigned buffer. A trigger can be a software API call or a hardware event. Continuous: The conversions of an ADC channel group are performed continuously after a software API call (start). The conversions themselves are running automatically (hardware/interrupt controlled). The Continuous conversions can be stopped by a software API call (stop).
Sampling Time	Time during which the analogue value is sampled (e.g. loading the capacitor, …)
Conversion Time	Time during which the sampled analogue value is converted into digital representation.
Acquisition Time	Sample Time + Conversion Time
