The watch dog timer WDTon the other hand, is composed of an 8-stage time base generator along with a 2-stage count-up counter, and is designed to break the host controller or other subsystems from abnormal states such as unknown or unwanted hoptek, execution errors, etc.

The crystal oscillator option can be applied to connect an external frequency source of 32kHz to the OSCI pin. Before placing purchase order re-validate quotation. This page was last edited on 10 Augustat Command The mode command should be issued before the data or command is transferred. The bold form of 1 0 0, namely 1 0 0, indicates the command mode ID.

That is, after the external clock source is selected, the HT will continue working until system power holtdk or the external clock source is removed. View the annotations at Commons. The clocked out data will appear on the DATA line. In this case, the system fails to enter the power down mode, similar to the case in the external kHz clock source operation.

It is recommended that the host controller read in correct data during the interval between the rising hoptek and the next falling edge of the RD signal. If the VDD drops below the minimum voltage of operating voltage spec.

It is recommended that the host controller should read in the data from the DATA line between the rising edge of the RD line and the falling edge of the next RD line.

The value of the capacity depends on how accurate the crystal is. But if the external clock source is chosen as the system clock, using the SYS DIS command can neither turn the oscillator off nor carry out the power down mode.

Tevion MD – Push button contact surface Chip selection BZ, BZ: But if CS is at logic low level and is input to the CS pad, the data and command transmission between the host controller and the HT are all enabled. However, Holtek assumes no responsibility arising from the use of the specifications described. If an on-chip oscillator kHz or an external kHz frequency is chosen as the source of the system frequency, the frequency source is by default prescaled to 32kHz by a 3-stage prescaler.
