output.
Tristates the OPT_TX output.
Indicates that the preboot sequence is active.
Together w/ SUM_CYCLES, this value determines the number of
samples in one sum cycle between XFER interrupts for the CE.
Number of samples = PRE_SAMPS*SUM_CYCLES.
The RTC interface. These are the ‘year’, ‘month’, ‘day’, ‘hour’,
‘minute’ and ‘second’ parameters for the RTC. The RTC is set by
writing to these registers. Year 00 is defined as a leap year.
RTC time correction bits. Only one bit may be pulsed at a time. When
pulsed, causes the RTC time value to be incremented (or
decremented) by an additional second the next time the RTC_SEC
register is clocked. The pulse width may be any value. If an additional
correction is desired, the MPU must wait 2 seconds before pulsing
one of the bits again.
Real Time Monitor enable. When ‘0’, the RTM output is low. This bit
enables the two wire version of RTM
Four RTM probes. Before each CE code pass, the values of these
registers are serially output on the RTM pin. The RTM registers are
ignored when RTM_EN=0.
Enables security provisions that prevent external reading of flash
memory and CE program RAM. This bit is reset on chip reset and
may only be set. Attempts to write zero are ignored.
Enables the Synchronous Serial Interface (SSI) on SEG3, SEG4, and
SEG5 pins. If SSI_RDYEN is set, SEG6 is enabled also. The pins take
on the new functions SCLK, SSDATA, SFR, and SRDY, respectively.
When SSI_EN is high and LCD_EN is low, these pins are converted to
the SSI function, regardless of LCDEN and LCD_NUM. For proper
LCD operation, SSI_EN must not be high when LCD_EN is high.
SSI clock speed: 0: 5MHz, 1: 10MHz
SSI gated clock enable. When low, the SCLK is continuous. When
high, the clock is held low when data is not being transferred.
SSI frame pulse format:
0: once at beginning of SSI sequence (whole block of data),
1: every 8 bits, 2: every 16 bits, 3: every 32 bits.
SFR pulse polarity: 0: positive, 1: negative
