For example, the HW/SW pin selects between Hardware (HW) mode and
Software (SW) mode. When the signal level on the HW/SW pin is logic:
A bit in a register is identified using the format ‘register.bit’. For example, bit
0.15 is bit 15 of register 0.
When a colon is used with bits, it indicates the range of bits. For example,
bits 1.15:11 are bits 15, 14, 13, 12, and 11 of register 1.
For a range of bits, the order is always from the most-significant bit to the
least-significant bit.
‘Bits’
‘Pin (or signal) names’
As a default, all numbers use the decimal system (that is, base 10) unless
followed by a lowercase letter. A string of numbers followed by a lowercase
letter:
– A ‘b’ represents a binary (base 2) number
– An ‘h’ represents a hexadecimal (base 16) number
– An ‘o’ represents an octal (base 8) number
All numerical references to registers use decimal notation (and not
hexadecimal).
All pin or signal names are provided in capital letters.
A pin name that includes a forward slash ‘/’ is a multi-function, configuration
pin. These pins provide the ability to select between two ICS1893AF
functions. The name provided:
– Before the ‘/’ indicates the pin name and function when the signal level
– After the ‘/’ indicates the pin name and function when the signal level on
– Zero, the ICS1893AF Hardware mode is selected.
– One, the ICS1893AF Software mode is selected.
An ‘n’ appended to the end of a pin name or signal name (such as
RESETn) indicates an active-low operation.
When a colon is used with pin or signal names, it indicates a range. For
example, TXD[3:0] represents pins/signals TXD3, TXD2, TXD1, and TXD0.
When pin name abbreviations are spelled out, words in parentheses
indicate additional description that is not part of the pin name abbreviation.
A bit in a register is identified using the format ‘register.bit’. For example, bit
0.15 is bit 15 of register 0.
All numerical references to registers use decimal notation (and not
hexadecimal).
When register name abbreviations are spelled out, words in parentheses
indicate additional description that is not part of the register name
abbreviation.
