Address Map
Table 2 (Timekeeper Registers) shows the address map for the IDT1337 registers. During a multibyte access, when the
address pointer reaches the end of the register space (0Fh), it wraps around to location 00h. On an I2C START, STOP, or
address pointer incrementing to location 00h, the current time is transferred to a second set of registers. The time
information is read from these secondary registers, while the clock may continue to run. This eliminates the need to re-read
the registers in case of an update of the main registers during a read.

Note: Unless otherwise specified, the state of the registers are not defined when power is first applied or when VCC falls below the
