Preliminary
The SRAM bank point register can switch to ei-
ther external 256 Kbytes or internal 32 Kbytes
SRAMspace.Theselectiontableisbasedonthe
following table. The space size of each SRAM
bank is 8 Kbytes. Bits BP_MODS1 and
BP_MODS0 define whether internal or exter-
nal SRAM devices are used. (BP_MODS1,
BP_MODS0)=(0, 1), is for internal SRAM de-
vices. (BP_MODS1, BP_MODS0)=(1, 0), is for
external SRAM devices. The internal SRAM
would switch from bank 0 to bank 3 and the ex-
ternal SRAM would switch from bank 0 to bank
31 by software programming. In addition, the
address range of the internal/external SRAM
will all range from 3000H to 4FFFH.

The LCD control and command registers are
used for LCD driver interface. There are three
kinds of LCD driver chips available for the
HT9580. These LCD drivers are SED15X(KSX)
series, Motorola LCD driver chip MC141X se-
ries and HD66410 respectively according to the
following LCD-CHIP0 and LCD-CHIP1 bit
table settings. The combination of the
LCD_CMD and LCD-CTRL registers can con-
trol the SED15X(KSX), MC141X series or
HD66410 LCD drivers. Bits LCD-CS0/1 of the
LCD-CTRL register corresponds to the chip se-
lect pin of the LCD driver. The bit LCD-CS0 is
used to control the master LCD driver chip
while LCD-CS1 is for the slave LCD driver
chip. Both bits are active low. The bit
CLK_MOD is used to enable or disable the
pin out of LCD_CL. If the bit is set low, the
clock output of pin LCD_CL will be disabled,
otherwise the LCD_CL clock will be set accord-
ing to the following Truth Table.
