DS70197C-page 1-4 © 2007-2012 Microchip Technology Inc. Section 1. Introduction 1.5 1 STYLE AND SYMBOL CONVENTIONS Table 1-2: Document Conventions Symbol/Term Description Set To force a bit/register to a value of logic ‘1’. Clear To force a bit/register to a value of logic ‘0’. Reset To force a register/bit to its default state. A reset is a condition, in which the device places itself after a device Reset occurs. Some bits will be forced to ‘0’ (such as interrupt enable bits), while others will be forced to ‘1’ (such as the I/O data direction bits). R-M-W Read-Modify-Write. This is when a register or port is read, then the value is modified and that value is then written back to the register or port. This action can occur from a single instruction (such as BSET) or a sequence of instructions. : (colon) Specifies a range or concatenation of registers/bits/pins. Concatenation order (left to right) usually specifies a positional relationship (MSb to LSb, higher to lower). For example, TMR3:TMR2 indicates the concatenation of two 16-bit registers to form a 32-bit timer value, with the value of TMR3 representing the most significant word of the value. <> (angle brackets) Specifies a bit location or range of locations within a particular register or field of similarly named bits. For example, OSCCON<14:12> or COSC<2:0>, specifies the register and associated bits or bit positions. MSb, LSb Indicates the Most Significant bit and Least Significant bit. MSB, LSB Indicates the Most Significant Byte and Least Significant Byte. lsw, msw Indicates the least significant or most significant word in a field of bits. 0xnn Designates the number ‘nn’ in the hexadecimal number system. This convention, which is always preceded by 0x, is used in code examples and text. For example, 0x13 is equivalent to 13h. ‘bnnn Designates the binary number ‘‘bnnn’. For example, the designation ‘b101 may be used. Font Conventions: Arial The standard font used for all text, figures and tables within this manual. Other fonts, as described below, are used to set off mathematical and logical expressions, or device instruction code, from descriptive text. Courier New Within text, this font is used for contrast with the standard text font and specifically denotes the following: • An instruction set mnemonic or assembler code fragment • The binary value of a bit, range of bits or a register • The logical state of a digital signal Within code examples, this font is used exclusively to denote a programming language or high-level language instruction sequence. Times New Roman The standard font for mathematical expressions and variables. (Italics) M ( PLLDIV + 2 ) F VCO = F IN × ⎛ -------⎞ = F IN × ⎛ -------------------------------------⎞ ⎝ N1⎠ ⎝ ( PLLPRE + 2 )⎠ Graphic Conventions: Note A Note presents information that we want to re-emphasize, either to help you avoid a common pitfall or to make you aware of operating differences between some device family members. A Note can be in a box, and is located at the bottom of the table, figure, or register. Register cells A bit reference that appears in a gray shaded cell of a register, signifies that the bit is either unimplemented (instead of a name, an EM dash (—) is present) or is not relevant to the particular peripheral module. © 2007-2012 Microchip Technology Inc. DS70197C-page 1-5 Introduction Throughout the individual family reference manual sections, certain style, format and font conventions are used to indicate specific distinctions to the emphasized text. Table 1-2 lists these conventions, the specific symbols, and non-conventional word definitions and abbreviations. dsPIC33F/PIC24H Family Reference Manual 1.5.1 Electrical Specifications The individual family reference manual sections contain references to electrical specifications and their parameter numbers. Table 1-3 shows the parameter numbering convention for dsPIC33F/PIC24H devices. A parameter number represents a unique set of characteristics and conditions that is consistent between every data sheet, although the actual parameter value may vary from device to device. To determine the parameter values for a specific device, “Electrical Characteristics” chapter in the specific device data sheet. Table 1-3: refer to the Electrical Specification Parameter Numbering Convention Parameter Number Format Comment Dxxx DC Specification Axxx DC Specification for Analog Peripherals xxx PDxxx Pxxx Timing (AC) Specification Device Programming DC Specification Device Programming Timing (AC) Specification Legend: ‘xxx’ represents a parameter number. 1.6 RELATED DOCUMENTS Microchip, as well as other sources, offers additional documentation that can assist in your development with dsPIC33F/PIC24H devices.
