One-Second Counter—Decrements with every clock pulse of Channel 1's transmit clock
(TXCKI) and rolls over when it reaches zero. The default value 02aa9e00(h) is equivalent to
one second at the DS3 clock rate. When the counter rolls over, the value programmed into this
counter is automatically reloaded and the count-down continues. Reading this address
provides the current value of the counter itself and not the programmed value written to this
address. When programming this register, the One-Second Latching mode is disabled, and the
OneSecMod bit is cleared in Register GCR01, the General2 Control register.
If the system is set to internal one-second triggering when the counter rolls over, the OneSecItr
bit in Register GSR00, the Source Channel Status register, is set. If, at the same time, the
1SecTimIE bit is also set in GCR01, the General2 Control register, an interrupt on the INTR*
pin occurs.
