XHOLD and XHOLDA
If the HOLD mode bit is set while XHOLD and XHOLDA are both low (external bus accesses granted), the
XHOLDA signal is forced high (at the end of the current cycle) and the external interface is taken out of
high-impedance mode.
On a reset (XRS), the HOLD mode bit is set to 0. If the XHOLD signal is active low on a system reset, the bus
and all signal strobes must be in high-impedance mode, and the XHOLDA signal is also driven active low.
When HOLD mode is enabled and XHOLDA is active low (external bus grant active), the CPU can still execute
code from internal memory. If an access is made to the external interface, the CPU is stalled until the XHOLD
signal is removed.
An external DMA request, when granted, places the following signals in a high-impedance mode:
XA[18:0]
XD[15:0]
XWE, XRD
XR/W
XZCS0AND1
XZCS2
XZCS6AND7
All other signals not listed in this group remain in their default or functional operational modes during these
signal events. Detailed timing diagram will be released in a future revision of this data sheet.
