Description
Enables timed flash writes. When 1, and if CE_E = 1, flash write requests are
FLSH_PSTWR

R/W
stored in a one-element deep FIFO and are executed when CE_BUSY falls.
FLSH_PEND can be read to determine the status of the FIFO. If
FLSH_PSTWR = 0 or if CE_E = 0, flash writes are immediate.

0 = MOVX commands refer to External RAM Space, normal operation (default).

R/W 1 = MOVX @ DPTR ,A moves A to External 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.

Must be a ‘2’ to enable any flash modification. See the description of Flash
security for more details.
Indicates that the flash may be written through ICE or SPI slave ports.

Interrupt flags for external interrupts 2 and 6. These flags monitor the source
of the int6 and int2 interrupts (external interrupts to the MPU core). These
flags are set by hardware and must be cleared by the software interrupt

automatically cleared by the MPU core when it vectors to the interrupt

bit positions in SFR 0xC0, while writing ones to the other bit positions that are
not being cleared.

interrupts INT0, INT1, up to INT6. These bits do not have any memory and
are primarily intended for debug use.

Configures SEG/COM bits as COM. Has no effect on pins whose LCD_MAP
bit is zero.

R/W Connects the LCD power supply to VBAT in all modes.
Identifies which segments connected to SEG23 and SEG22 should blink. 1
R/W means ‘blink.’ The most significant bit corresponds to COM5, the least
significant, to COM0.
