GIO
General Input/Output
GPIO
General Purpose Input/Output
GPR
General Purpose Register (RAM). A portion of the data memory that can be used to store the
program’s dynamic variables.
Harvard Architecture
In this architecture the Program Memory and Data Memory buses are separated. This allows
concurrent accesses to Data Memory and Program Memory, which increases the performance
of the device.
Holding Capacitor
This is a capacitor in the Analog to Digital (A/D) module which “holds” to analog input level once
the conversion is started. During acquisition, the holding capacitor is charged/discharged by the
voltage level on the analog input pin. Once the conversion is started, the holding capacitor is dis-
connected from the analog input and “holds” this voltage for the A/D conversion.
HS
High Speed. One of the device oscillator modes. The oscillator circuit is tuned to support the high
frequency operation. Used for operation from 4 MHz to 20 MHz.
