R/W
Non-volatile general-purpose registers powered by the RTC supply. These registers
maintain their value in all power modes, but will be cleared on reset. The values of
GP0…GP7
will be undefined if VBAT drops below the minimum value.

R/W
R/W
Interrupt flags for the Firmware Collision Interrupt. See the Flash Memory section for
details.
IE_PB
SFR E8[4] 0 – R/W
PB flag. Indicates that a rising edge occurred on PB. Firmware must write a zero to
this bit to clear it. The bit is also cleared when the MPU requests SLEEP or LCD
mode. On bootup, the MPU can read this bit to determine if the part was woken with
the PB DIO0[0].
IE_PLLRISE
SFR E8[6] 0 0 R/W
Indicates that the MPU was woken or interrupted (INT4) by system power becoming
available, or more precisely, by PLL_OK rising. The firmware must write a zero to this
bit to clear it.
IE_PLLFALL
SFR E8[7] 0 0 R/W
Indicates that the MPU has entered BROWNOUT mode because system power has
become unavailable (INT4), or more precisely, because PLL_OK fell. This bit will not
be set if the part wakes into BROWNOUT mode because of PB or the WAKE timer.
The firmware must write a zero to this bit to clear it.
IEN_SPI

R/W
SPI interrupt enable.

R/W
Interrupt flags. These flags monitor the XFER_BUSY interrupt and the RTC_1SEC
interrupt. The flags are set by hardware.
IE_WAKE
SFR E8[5] 0
–
R/W
Indicates that the MPU was awakened by the autowake timer. This bit is typically read
by the MPU on bootup. The firmware must write a zero to this bit to clear it.
INTBITS
SFR F8[6:0] –
–
R/W
Interrupt inputs. The MPU may read these bits to see the status of external interrupts
INT0, INT1 up to INT6. These bits do not have any memory and are primarily intended
for debug use.
