Note:
Table 17. Stop-Mode Recovery Source
Stop-Mode Recovery Delay Select (D5)
This bit, if low, disables the 5 ms RESET delay after Stop-Mode Recovery. The
default configuration of this bit is 1. If the “fast” wake up is selected, the Stop-
Mode Recovery source must be kept active for at least 5 TpC.
Stop-Mode Recovery Edge Select (D6)
A 1 in this bit position indicates that a High level on any one of the recovery
sources wakes the Z86D73 from STOP Mode. A 0 indicates Low level recovery.
The default is 0 on POR.
Cold or Warm Start (D7)
This bit is read only. It is set to 1 when the device is recovered from Stop Mode.
The bit is set to 0 when the device reset is other than Stop Mode Recovery (SMR).

Any Port 2 bit defined as an output drives the corresponding
input to the default state. This condition allows the remaining
inputs to control the AND/OR function. Refer to SMR2 register
on page 63 for other recover sources.
