8.1 General description
The SAA7893HL is capable to communicate with the hosts (families) via their own
busses as given in
Table 5:
The type of host is selected via two input pins H_sel[1] and H_sel[0] and the proc_clk
signal. In
input clock(s).
Table 6:
In all modes the range of the required internal system clock is between
27 and 35 MHz.
The pin mapping in the different modes is shown in
