Description
Controls the speed of the PLL and MCK.
1 = 19.66 MHz (XTAL * 600)
0 = 6.29 MHz (XTAL * 192)
PLS_MAXWIDTH[7:0] determines the maximum width of the pulse (low-going
pulse if PLS_INV=0 or high-going pulse if PLS_INV=1). The maximum pulse
width is (2*PLS_MAXWIDTH[7:0] + 1)*T
units of CK_FIR clock cycles. If PLS_INTERVAL[7:0] = 0 or
PLS_MAXWIDTH[7:0] = 255, no pulse width checking is performed and the
output pulses have 50% duty cycle. See
PLS_INTERVAL[7:0] determines the interval time between pulses. The time
between output pulses is PLS_INTERVAL[7:0]*4 in units of CK_FIR clock
cycles. If PLS_INTERVAL[7:0] = 0, the FIFO is not used and pulses are output
as soon as the CE issues them. PLS_INTERVAL[7:0] is calculated as follows:
PLS_INTERVAL[7:0]
updates per Mux frame / 4 )
For example, since the 71M654x CE code is written to generate 6 pulses in one
integration interval, when the FIFO is enabled (i.e., PLS_INTERVAL[7:0] ≠ 0)
and that the frame duration is 1950 CK_FIR clock cycles, PLS_INTERVAL[7:0]
should be written with Floor(1950 / 6 / 4) = 81 so that the five pulses are
evenly spaced in time over the integration interval and the last pulse is issued
just prior to the end of the interval. See
Inverts the polarity of WPULSE and VARPULSE. Normally, these pulses are
active low. When inverted, they become active high. PLS_INV has no effect
on XPULSE or YPULSE.
Enables outputs from the pins SEGDIO0-SEGDIO15. PORT_E = 0 after reset
and power-up blocks the momentary output pulse that would occur on
SEGDIO0 to SEGDIO15.
Indicates that pre-boot sequence is active.
When the MPU writes a non-zero value to RCMD[4:0], the IC issues a
command to the appropriate remote sensor. When the command is complete,
the IC clears RCMD[4:0].
When set, writes a one to WF_RSTBIT and then causes a reset.
Controls how the IC drives the power pulse for the 71M6x01. When set, the
power pulse is driven high and low. When cleared, it is driven high followed
by an open circuit fly-back interval.
