Numeric Naming
Hexadecimal numbers are represented with all letters in uppercase with an appended lowercase ‘h’ (for example, ‘14h’ or ‘3Ah’).
Hexadecimal numbers may also be represented by a ‘0x’ prefix, the C coding convention. Binary numbers have an appended
lowercase ‘b’ (for example, 01010100b’ or ‘01000011b’). Numbers not indicated by an ‘h’, ‘b’, or 0x are decimal.

Connection between any GPIO combination via analog multiplexer bus.
Ideally, any two adjacent digital codes correspond to output analog voltages that are exactly
one LSB apart. Differential non-linearity is a measure of the worst case deviation from the
ideal 1 LSB step.
Hold time is the time following a clock event during which the data input to a latch or flip-
flop must remain stable in order to guarantee that the latched data is correct.
It is a serial multi-master bus used to connect low speed peripherals to MCU.
It is a term describing the maximum deviation between the ideal output of a DAC/ADC and
the actual output level.
Current at which the latch-up test is conducted according to JESD78 standard (at 125
degree Celsius)
The PSRR is defined as the ratio of the change in supply voltage to the corresponding
change in output voltage of the device.
The conversion of all sensor capacitances to digital values.
Period required to prepare a device, machine, process, or system for it to be ready to
function.
The ratio between a capacitive finger signal and system noise.
Serial peripheral interface is a synchronous serial data link standard.
