Manual Objective
PICmicro devices are grouped by the size of their Instruction Word. The three current PICmicro
families are:
1.
2.
3.
This manual focuses on the Mid-Range devices, which are also referred to as the PIC16CXXX
MCU family.
The operation of the PIC16CXXX MCU family architecture and peripheral modules is explained,
but does not cover the specifics of each device. Therefore, it is not intended to replace the device
data sheets, but complement them. In other words, this guide supplies the general details and
operation of the PICmicro architecture and peripheral modules, while the data sheet s give spe-
cific details such as device memory mapping.
Initialization examples are given throughout this manual. These examples sometimes need to be
written as device specific as opposed to family generic, though they are valid for most other
devices. Some modifications may be required for devices with variations in register file mappings.
Note:
Base-Line:
Mid-Range: 14-bit Instruction Word length
High-End:
The first few Mid-Range devices have minor device variations when compared to
this general description. We have tried to describe these variations throughout this
manual. Please refer to the specific device data sheet for complete information on
the device.
