;****************************************************************************
; Purpose of program to initialize Digital Speaker part via I2C; perform
; start up of the equalizer board; and act as interface between multifunction
; key switches and Digital Speaker part. 430 does not have to read data from
; DS part (other than acknowledge) so read routines deleted to save memory
; space. Arbitration also deleted since 430 is the only part transmitting
; data.
;
;
rev 2.4G - unchanged delay changes in rev F back to rev C, including
;
additional delay0 added in F, after finding typo in rev F.
