; Revision history:
;
; 4/12/02: Commented out the line which wrote to the SCSR1 to set up the
;          PLL. The PLL is set up in the boot ROM code, and there is 
;          a selection mechanism to select x2 or x4 mode for the PLL.
;          This over-wrote that selection causing the programmer to fail
;          when the x2 option was selected, since only the pll register
;          got changed, while the baud rate register in the SCI remained 
;          the same.
