Section 18 Host Interface X-Bus Interface (XBS)
command is detected, bit 1 of the data following the host command is output from the GA20
output pin. This operation does not depend on firmware or interrupts, and is faster than the regular
processing using interrupts. Table 18.5 lists the conditions that set and clear GA20 (P81). Figure
18.2 shows the GA20 output in flowchart form. Table 18.6 indicates the GA20 output signal
values.
