SMARTWATCH REGISTER INFORMATION
The SmartWatch information is contained in eight registers of 8 bits, each of which is sequentially
accessed one bit at a time after the 64-bit pattern recognition sequence has been completed. When
updating the SmartWatch registers, each must be handled in groups of 8 bits. Writing and reading
individual bits within a register could produce erroneous results. These read/write registers are defined in
Figure 3.
Data contained in the SmartWatch registers is in binary-coded decimal format (BCD). Reading and
writing the registers is always accomplished by stepping through all eight registers, starting with bit 0 of
register 0 and ending with bit 7 of register 7.
AM–PM/12/24 MODE
Bit 7 of the hours register is defined as the 12-hour or 24-hour mode-select bit. When high, the 12-hour
mode is selected. In the 12-hour mode, bit 5 is the AM/PM bit with logic high being PM. In the 24-hour
mode, bit 5 is the second 10-hour bit (20–23 hours).
OSCILLATOR AND RESET BITS
Bits 4 and 5 of the day register are used to control the
RESET
and oscillator functions. Bit 4 controls the
RESET
(pin 1). When the
RESET
bit is set to logic 1, the
RESET
input pin is ignored. When the
RESET
bit
is set to logic 0, a low input on the
RESET
pin will cause the SmartWatch to abort data transfer without
changing data in the watch registers. Bit 5 controls the oscillator. When set to logic 1, the oscillator is off.
When set to logic 0, the oscillator turns on and the watch becomes operational. These bits are shipped
from the factory set to logic 1.
ZERO BITS
Registers 1, 2, 3, 4, 5, and 6 contain one or more bits that will always read logic 0. When writing these
locations, either a logic 1 or 0 is acceptable.
ADDITIONAL INFORMATION
Refer to Application Note 52 for information about using regarding optional modifications and the
phantom clock contained within the SmartWatch.
