Freescale Semiconductor

14.6.7 Time-of-Day Minutes Alarm Register (TODMAL)

14.6.7.1 Reserved—Bits 15–6

These bits are reserved or not implemented. They cannot be read nor modified by writing.

14.6.7.2 Time-of-Day Minutes Alarm (TODMAL)—Bits 5–0

When the value contained in this register matches the value of the minutes counter, the minutes

alarm is asserted if the Minutes Alarm Enable (TODMA) bit and Alarm Interrupt Enable

(TODAEN) bit are both set, and all other enabled alarm registers also match the current time.

14.6.8 Time-of-Day Hours Register (TODHR)

14.6.8.1 Reserved—Bits 15–6

These bits are reserved or not implemented. They cannot be read nor modified by writing.

14.6.8.2 Time-of-Day Hours (TODHR)—Bits 5–0

When TODEN is set, this register is continuously updated to contain the current hours counter

value. The value of the counter can be read through the hours register, but it can not be modified.

When TODEN is cleared, TOD counting is disabled. This register can then be read or written.

When TODEN is set to one again, the counting resumes from the current register value.
