Description
FLSH_PGADR
SFR
B7[7:1]
W
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.
FLSH_PWE
SFR B2[0]
R/W
Program Write Enable
0 – MOVX commands refer to XRAM Space, normal operation (default).
1 – MOVX @DPTR,A moves A to Program Space (Flash) @ DPTR.
This bit is automatically reset after each byte written to flash. Writes to this
bit are inhibited when interrupts are enabled.
IE_XFER
IE_RTC
SFR E8[0]
SFR E8[1]
R/W
Interrupt flags. These flags are part of the WDI SFR register and monitor 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.
INTBITS
SFR
F8[6:0]
R
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.
LCD_BSTEN

R/W
Enables the LCD voltage boost circuit.
LCD_CLK[1:0]
2021[1:0]
