PIC12(L)F1571/2
8-Pin MCU with High-Precision 16-Bit PWMs
Description:
PIC12(L)F1571/2 microcontrollers combine the capabilities of 16-bit PWMs with Analog to suit a variety of applications.
These devices deliver three 16-bit PWMs with independent timers for applications where high resolution is needed, such
as LED lighting, stepper motors, power supplies and other general purpose applications. The core independent

1.1 Register and Bit Naming
Conventions
1.1.1 REGISTER NAMES
When there are multiple instances of the same
peripheral in a device, the peripheral control registers
will be depicted as the concatenation of a peripheral
identifier, peripheral instance and control identifier. The
control registers section will show just one instance of
all the register names with an ‘x’ in the place of the
peripheral instance number. This naming convention
may also be applied to peripherals when there is only
one instance of that peripheral in the device to maintain
compatibility with other devices in the family that
contain more than one.
1.1.2 BIT NAMES
There are two variants for bit names:
• Short name: Bit function abbreviation
• Long name: Peripheral abbreviation + short name
1.1.2.1 Short Bit Names
Short bit names are an abbreviation for the bit function.
For example, some peripherals are enabled with the
EN bit. The bit names shown in the registers are the
short name variant.
Short bit names are useful when accessing bits in C
programs. The general format for accessing bits by the
short name is RegisterNamebits.ShortName. For
example, the enable bit, EN, in the COG1CON0 regis-
ter can be set in C programs with the instruction,
COG1CON0bits.EN = 1.
Short names are generally not useful in assembly
programs because the same name may be used by
different peripherals in different bit positions. When this
occurs, during the include file generation, all instances
of that short bit name are appended with an
underscore, plus the name of the register in which the
bit resides, to avoid naming contentions.
