c) 24/12 (D
2) (24-hour clock/12-hour clock)
This bit selects a 24-hour clock or 12-hour clock mode. When the bit is 1, the 24-hour clock
mode without PM/AM specification is enabled. When the bit is 0, the 12-hour clock mode
with PM or AM specified is enabled.
When the 24/12 bit is rewritten, data in the R-H
1 register and higher will be destroyed. The
data needs to be written again.
d) HD/SFT (D
3) (HarDware/SoFTware)(This bit applicable only to the MSM6542-03)
This bit determines which mode, hardware or software, is enabled to validate the stop/start
function. When the bit is 1, hardware enables the stop/start function (pin 20). When the bit
is 0, software enables the stop/start function (D
2 of the CF register)
The stop/start function by hardware and that by software cannot be used at the same time.
For the MSM6542-01/02, the stop/start function by software is always enabled due to an
internal setting on the IC. However, the HD/SFT bit can be read or written to freely
regardless of this setting, enabling the bit to be used as a memo bit.
