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 16.

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.
Flash Erase Initiate
FLSH_ERASE is used to initiate either the Flash Mass Erase cycle or
the Flash Page Erase cycle. Specific patterns are expected for
FLSH_ERASE in order to initiate the appropriate Erase cycle.
(default = 0x00).
0x55 – Initiate Flash Page Erase cycle. Must be proceeded by a write
0xAA – Initiate Flash Mass Erase cycle. Must be proceeded by a write
Any other pattern written to FLSH_ERASE will have no effect.
Programs the direction of DIO pins 15 through 8. 1 indicates output.
Ignored if the pin is not configured as I/O.
Programs the direction of DIO pins 21 through 16. 1 indicates output.
