Table 96. ZDI Read/Write Control Register Functions (ZDI_RW_CTL = 16h in
the ZDI Register Write-Only Address Space)
ZDI Bus Control Register
The ZDI Bus Control register controls bus requests during DEBUG mode. It enables or
disables bus acknowledge in ZDI DEBUG mode and allows ZDI to force assertion of the
BUSACK signal. This register must be written during ZDI Debug mode (that is, following
a BREAK). See
Table 97. ZDI Bus Control Register (ZDI_BUS_CTL = 17h in the ZDI Register
