The number of states in the input multiplexer.
Selects OPT_TX modulation duty cycle
OPT_RX can be configured as an analog input to the optical UART
comparator or as a digital input/output, DIO1.
0—OPT_RX, 1—DIO1.
Inverts result from OPT_RX comparator when 1. Affects only the
UART input. Has no effect when OPT_RX is used as a DIO input.
Configures the OPT_TX output pin.
00—OPT_TX, 01—DIO2, 10—WPULSE, 11—VARPULSE
Invert OPT_TX when 1. This inversion occurs before modulation.
Enables modulation of OPT_TX. When OPT_TXMOD is set,
OPT_TX is modulated when it would otherwise have been zero.
The modulation is applied after any inversion caused by
OPT_TXINV.
Indicates that system power is present and the clock generation PLL
is settled.
Determines the maximum width of the pulse (low going pulse).
Maximum pulse width is (2*PLS_MAXWIDTH + 1)*T
PLS_INTERVAL. If PLS_INTERVAL=0, T
(397µs). If 255, disable MAXWIDTH.
If the FIFO is used, PLS_INTERVAL must be set to 81. If
PLS_INTERVAL = 0, the FIFO is not used and pulses are output as
soon as the CE issues them.
Inverts the polarity of WPULSE and VARPULSE. Normally, these
pulses are active low. When inverted, they become active high.
Indicates that preboot sequence is active.
The duration of the pre-summer, in samples.
The RTC interface. These are the ‘year’, ‘month’, ‘day’, ‘hour’,
‘minute’ and ‘second’ parameters of the RTC. The RTC is set by
writing to these registers. Year 00 and all others divisible by 4 are
defined as leap years.
Each write to one of these registers must be preceded by a write to
201F (WE).
