* instructions
* *Note: A value of X for address is a don't care condition.
* **Note: There are 8 address bits for the 93C56/66 chips unlike
* the 93C46/26/06 chips which have 6 address bits.
*
* The 93C46 has a four wire interface: clock, chip select, data in, and
* data out. In order to perform one of the above functions, you need
* to enable the chip select for a clock period (typically a minimum of
* 1 usec, with the clock high and low a minimum of 750 and 250 nsec
* respectively). While the chip select remains high, you can clock in
* the instructions (above) starting with the start bit, followed by the
* OP code, Address, and Data (if needed). For the READ instruction, the
* requested 16-bit register contents is read from the data out line but
* is preceded by an initial zero (leading 0, followed by 16-bits, MSB
* first). The clock cycling from low to high initiates the next data
* bit to be sent from the chip.

/*
* This file defines five types of data structures: singly-linked lists,
* singly-linked tail queues, lists, tail queues, and circular queues.
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A singly-linked tail queue is headed by a pair of pointers, one to the
* head of the list and the other to the tail of the list. The elements are
* singly linked for minimum space and pointer manipulation overhead at the
* expense of O(n) removal for arbitrary elements. New elements can be added
* to the list after an existing element, at the head of the list, or at the
* end of the list. Elements being removed from the head of the tail queue
* should use the explicit macro for this purpose for optimum efficiency.
* A singly-linked tail queue may only be traversed in the forward direction.
* Singly-linked tail queues are ideal for applications with large datasets
* and few or no removals or for implementing a FIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.
