Msk1:

On writes, set this bit to mask bits 14..8. This prevents previous settings of bits 14..8 from being changed.

 

 

 

 

 

 

 

 

 

 

 

 

 

MP:

Minute Pulse (read only): Current State of Minute-Pulse signal (at the time of the read).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

MPP:

Minute Pulse Pending (read only): This bit is set to the same state as the MPO bit (when the MPO bit is written). When the MPO is

 

 

 

 

 

 

 

 

written high, this bit goes low (=0) when the next selected Minute-Pulse edge occurs.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

MPO:

Minute Pulse Once: When low (=0), the selected Minute-Pulse edge always resets the Seconds value. When high (=1) the RTC

 

 

 

 

 

 

 

 

increment is inhibited, then when the first selected

Minute-Pulse edge occurs, the Seconds value will be zeroed, the MPP bit will be

 

 

 

 

 

 

 

 

cleared and the RTC increment will be enabled. All subsequent Minute-Pulses edges will be ignored.

 

 

 

 

 

 

 

 

 

 

 

 

 

IntEN:

Clock Interrupt Enable: Enable an interrupt to occur on each clock increment pulse. The Interrupt is cleared by reading (or writing) the

 

 

 

 

 

 

 

 

RTC Lower Word (the Minutes/Seconds counter) or by disabling the interrupt. There is a dedicated interrupt signal to the Coldfire for

 

 

 

 

 

 

 

 

the RTC interrupt.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

SE:

Seconds-Pulse Edge Select: Selects the edge (of the Seconds-Pulse) which causes the RTC increment, 0=falling, 1=rising.

 

 

 

 

 

 

 

 

 

 

EXT:

External Time Base Select: 0=Internal Timebase (1 Hz), 1=External Timebase.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ME:

Minute Edge select: Selects the edge (of the Minute-Pulse) which causes the RTC Seconds counter to be reset, 0=falling, 1=rising

 

 

 

 

 

 

 

Msk0:

On writes, set this bit to mask bits 6..0. This prevents previous settings of bits 6..0 from being changed.

 

 

 

 

 

 

 

 

 

 

 

 

 

H4..0

Hours Setting, or reading (a number between 0 and 23).
