Voltage Reference (V
A voltage level that can be used as a reference point for A/D conversions (A
trip point for comparators.
von Neumann Architecture
In this architecture the Program Memory and Data Memory are contained in the same area. This
means that accesses to the program memory and data memory must occur sequentially, which
affects the performance of the device.
W Register
See Working Register.
Watchdog Timer (WDT)
Used to increase the robustness of a design by recovering from software flows that were not
expected in the design of the product or other system related issues. The Watchdog Timer
causes a reset if it is not cleared prior to overflow. The clock source for a PICmicro is an on-chip
RC oscillator which enhances system reliability.
WDT
Watchdog Timer.
Working Register (W)
Can also be thought of as the accumulator of the device. Also used as an operand in conjunction
with the ALU during two operand instructions.
XT
One of the device oscillator modes. Used for operation from 100 kHz to 4 MHz.
