14.6.5 Time-of-Day Seconds Alarm Register (TODSAL)

Figure 14-6. TOD Seconds Alarm Register (TODSAL)

See Programmer’s Sheet on Appendix page B - 98

14.6.5.1 Reserved—Bits 15–6

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

14.6.5.2 Time-of-Day Seconds Alarm (TODSAL)—Bits 5–0

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

alarm is asserted if the Seconds Alarm Enable (TODSA) bit and Alarm Interrupt Enable

(TODAEN) bits are set and all other enabled alarm registers also match.

14.6.6 Time-of-Day Minutes Register (TODMIN)

14.6.6.1 Reserved—Bits 15–6

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

14.6.6.2 Time-of-Day Minutes (TODMIN)—Bits 5–0

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

value. The value of the counter can be read through the minutes register, but it cannot 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.
