trec bit
Bit D7 of clock register 04h contains the trec bit (TR). trec refers to the automatic
continuation of the deselect time after VCC reaches VPFD. This allows for a voltage settling
time before WRITEs may again be performed to the device after a power-down condition.
The trec bit will allow the user to set the length of this deselect time as defined by Table 6.

Initial power-on defaults
Upon initial application of power to the device, the following register bits are set to a '0' state:
watchdog register, FT, AFE, ABE, SQWE, and TR. The following bits are set to a '1' state:
ST, OUT, and HT (see Table 7).
