Method and apparatus for resetting a gray code counter

A method for resetting a gray code counter, the method comprising:

• in response to an indication that a data buffer controlled by the gray code counter has attained one of a plurality specified states, disabling any attempt to write to said data buffer until a reset value of a write pointer controlling said data buffer is reached;
• and
• in response to an indication that said data buffer controlled by the gray code counter has attained said one of said plurality of specified states, disabling any attempt to read from said data buffer until a reset value of a read pointer controlling said data buffer is reached.

A system for resetting a gray code counter, the system comprising:

• a decrementer for gradually decrementing one of a read pointer and a write pointer associated with said data buffer until a reset value of one of said read pointer and said write pointer is reached in response to an indication that a data buffer controlled by the gray code counter has attained one of a plurality specified states;
• and
• an incrementer for gradually incrementing one of a read pointer and a write pointer associated with said data buffer until a reset value of said one of said read pointer and said write pointer is reached in response to an indication that said data buffer controlled by the gray code counter is has attained one of said plurality of specified states.

A machine-readable storage, having stored thereon a computer program having a at least one code section for resetting a gray code counter, the at least one code section executable by a machine for causing the machine to perform the steps comprising:

• gradually altering a write pointer associated with a data buffer until a reset value of said write pointer is reached in response to an indication that said data buffer controlled by the gray code counter has attained one of a plurality specified states;
• and
• gradually altering a read pointer associated with said data buffer until a reset value of said read pointer is reached in response to an indication that said data buffer controlled by the gray code counter has attained one of said plurality of specified states.
