When set, converts DIO4 and DIO5 to interface with external
EEPROM. DIO4 becomes SCK and DIO5 becomes bi-directional SDA.
LCD_NUM must be less than 18.
Causes VARPULSE to be output on DIO7, if DIO7 is configured as
output. LCD_NUM must be less than 15.
Causes WPULSE to be output on DIO6, if DIO6 is configured as
output. LCD_NUM must be less than 17.

Emulator clock disable. When one, the emulator clock is disabled.
operations. If ECK_DIS is set, it should be done at least 1000ms after
power-up to give emulators and programming devices enough time to
complete an erase operation.
Specifies the power equation to the CE.
Interrupt enable bits. These bits enable the XFER_BUSY and the
RTC_1SEC interrupts to the MPU. Note that if either interrupt is to be
enabled, EX6 in the 80515 must also be set.
The length of the ADC decimation FIR filter.
1: 22 ADC bits/3 CK32 cycles (384 CKFIR cycles),
0: 21 ADC bits/2 CK32 cycles (288 CKFIR cycles)
Should be set to 1 to minimize supply current.
Programs the direction of DIO pins 15, 14 and 11 through 8. 1
indicates output. Ignored if the pin is not configured as I/O.
Programs the direction of DIO pins 17 and 16. 1 indicates output.
Ignored if the pin is not configured as I/O.
Note: Bit 2, Bit 3, Bit 4 and Bit 5 must be set to 1.
Note: Bit 4 and Bit 5 must be set to 1.
interface and thus preclude flash erase and programming
This bit is to be used with caution! Inadvertently setting
this bit will inhibit access to the part with the ICE
The value on the DIO pins. Pins configured as LCD will read
zero. When written, changes data on pins configured as
outputs. Pins configured as LCD or input will ignore writes.
