Detailed Description

Instances of this class handle access to the M41T81 real-time clock chip.

This constructor is used to initialize a DS1305 real-time clock over a specified McBSP interface.

Parameters:

`[in]`	apI2C	The tcDspI2c object to use for communication.
`[in]`	anAddr	The address of the M41T81 on the I2C bus.
`[in]`	anYear	Base year (epoch) for this real-time clock.

Default Destructor.

tsCLTime tcDspRtcM41T81::get_time ( unsigned short * apHundredths = NULL ) [virtual]

This routine reads the current time from the real-time clock and returns it as a 32-bit tsCLTime value.

void tcDspRtcM41T81::set_time ( tsCLTime asTime ) [virtual]

This routine provides an alternate interface to the set_time routine, using a tsCLTime value.

Parameters:

[in] asTime A tsCLTime structure representing the current time.

This routine sets the current time of the real-time clock using discrete year, month, day, hour, minute and second values.

The current epoch is updated if required.

Parameters:
