Description
The number of states in the input multiplexer.
Selects TX1 modulation duty cycle.
RX1 can be configured as an analog input to the UART1
comparator or as a digital input/output, DIO1.
0—RX1, 1—DIO1.
Inverts result from RX1 comparator when 1. Affects only
the UART1 input. Has no effect when RX1 is used as a
DIO input.
Configures the TX1 output pin.
00—TX1, 01—DIO2, 10—WPULSE, 11—VARPULSE
Invert TX1 when 1. This inversion occurs before
modulation.
Enables modulation of TX1. When TX1MOD is set, TX1 is
modulated when it would otherwise have been zero. The
modulation is applied after any inversion caused by
TX1INV.
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
Where T
the sample time (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).
