/* I assume that they think all registers are cleared to zero on a 7113 reset so
 * don't explicity write the zeros. These comments are accurate as Philips documents the 7113.
 * Data to initialize the SAA7113 (seems to only be used in external mode)
 * As this data is specific to the SAA7113 it applies to all SPCA50X twinned with a 7113
