Figure 4. ROM/Time Chip Interface
Time Chip Register Information
Time Chip information is contained in eight registers of 8 bits, each of which is sequentially accessed 1
bit at a time after the 64-bit pattern recognition sequence has been completed. When updating the Time
Chip 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 5.
Data contained in the Time Chip registers is in binary coded decimal format (BCD). Reading and writing
the registers is always accomplished by stepping though 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- 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 20-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 input. 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 Time Chip to abort data transfer without changing
data in the timekeeping registers. Reset operates independently of all other in-puts. Bit 5 controls the
oscillator. When set to logic 0, the oscillator turns on and the real time clock/calendar begins to
increment.
