Description
Programs the direction of pins DIO15-DIO14, DIO11-DIO8.
1 indicates output. Ignored if the pin is not configured as
I/O.
Programs the direction of pins DIO20- DIO19 and DIO17-
DIO16 (and DIO21 for the 68 QFN package). 1 indicates
output. Ignored if the pin is not configured as I/O.
The value on the pins DIO7-DIO1. DIO3 is only available
on the 68-pin package. Pins configured as LCD will read
zero. When written, changes data on pins configured as
outputs. Pins configured as LCD or input will ignore write
operations.
The value on the pins DIO15-DIO14 and DIO11-DIO8.
Pins configured as LCD will read zero. When written,
changes data on pins configured as outputs. Pins
configured as LCD or input will ignore write operations.
The value on the pins DIO20-DIO19, and DIO17-DIO16
(and DIO21 for the 68 QFN package). Pins configured as
LCD will read zero. When written, changes data on pins
configured as outputs. Pins configured as LCD or input
will ignore write operations.
When set, converts DIO4 and DIO5 to interface with
external EEPROM. DIO4 becomes SDCK and DIO5
becomes bi-directional SDATA. LCD_NUM must be less
than or equal to 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.
Serial EEPROM interface data.
Serial EEPROM interface control.
and thus preclude Flash erase and programming
operations. If ECK_ENA is set, it should be done at least
1000 ms after power-up to give emulators and
programming devices enough time to complete an erase
operation.
Specifies the power equation to be used by the CE.
Interrupt enable bits. These bits enable the XFER_BUSY,
the RTC_1SEC, the FirmWareCollision, and PLL
interrupts. Note that if one of these interrupts is to be
enabled, its corresponding EX enable bit must also be
set. See the Interrupts section for details.
The length of the ADC decimation FIR filter.
When FIR_LEN=1, the ADC has 2.370370x higher gain.
