Figure 2. PHANTOM CLOCK REGISTER DEFINITION
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 phantom clock 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 a logic 1.
ZERO BITS
Registers 1, 2, 3, 4, 5, and 6 contain one or more bits that always read logic 0. When writing these
locations, either a logic 1 or 0 is acceptable.
