R/W When set, converts DIO4 and DIO5 to interface with external EEPROM. DIO4 be-
comes SDCK and DIO5 becomes bi-directional SDATA.

R/W Causes VARPULSE to be output on DIO7.
R/W Causes WPULSE to be output on DIO6.
R/W Causes XPULSE to be output on DIO8.
R/W Causes YPULSE to be output on DIO9.

ECK_DIS
R/W Serial EEPROM interface control.
R/W Emulator clock disable. When ECK_DIS = 1, the emulator clock is disabled.
If ECK_DIS is set, the emulator and programming devices will be unable to
erase or program the device.

R/W Interrupt enable bits. These bits enable the XFER_BUSY, the RTC_1SEC, the Firm-
WareCollision (FWCOL) and PLL interrupts. Note that if one of these interrupts is to
be enabled, its corresponding MPU EX enable must also be set. See Section 1.4.9
Interrupts for details.
FIR_LEN[1:0]

R/W FIR_LEN[1:0] controls the length of the ADC decimation FIR filter and therefore con-
trols the time taken for each conversion.

R/W Flash bank. Memory above 32 KB is mapped to the MPU address space from 0x8000
to 0xFFFF in 32 KB banks. When MPU address[15] = 1, the address in flash is
mapped to FL_BANK[2:0], MPU Address[14:0]. FL_BANK is reset by the erase cycle.
