This bit is automatically reset after each byte written to flash. Writes to
this bit are inhibited when interrupts are enabled.
Mass Erase Enable
0 – Mass Erase disabled (default).
1 – Mass Erase enabled.
Must be re-written for each new Mass Erase cycle.
Flash Page Erase Address
FLSH_PGADR[6:0] – Flash Page Address (page 0 thru 127) that will
be erased during the Page Erase cycle. (default = 0x00).
Must be re-written for each new Page Erase cycle.
Program Write Enable
0 – MOVX commands refer to XRAM Space, normal operation
1 – MOVX @DPTR,A moves A to Program Space (Flash) @ DPTR.
Interrupt flags. These flags are part of the WDI SFR register and mo-
nitor the XFER_BUSY interrupt and the RTC_1SEC interrupt. The
flags are set by hardware and must be cleared by the interrupt handler.
See also WD_RST.
Interrupt inputs. The MPU may read these bits to see the input to
external interrupts INT0, INT1, up to INT6. These bits do not have any
memory and are primarily intended for debug use.
Enables the LCD voltage boost circuit.
Sets the LCD clock frequency for COM/SEG pins (not the frame rate.
Note: f
Enables the LCD display. When disabled, VLC2, VLC1, and VLC0 are
ground as are the COM and SEG outputs.
Controls the LCD full scale voltage, VLC2:
The LCD bias mode.
000: 4 states, 1/3 bias
001: 3 states, 1/3 bias
010: 2 states, ½ bias
011: 3 states, ½ bias
100: static display
