10.3 Global Configuration Registers (LDN: All)
10.3.1 Configure Control (Index=02h)
This register is write only. Its values are not sticky; that is to say, a hardware reset will automatically
clear the bits, and does not require the software to clear them.
Bit
Description
7-2 Reserved
1 Returns to the “Wait for Key” state. This bit is used when configuration sequence is completed.
0 Resets all logical devices and restores configuration registers to their power-on states.
10.3.2 Logical Device Number (LDN, Index=07h)
This register is used to select the current logical devices. By reading from or writing to the
configuration of I/O, Interrupt, DMA and other special functions, all registers of the logical devices can
be accessed. In addition, ACTIVATE command is only effective for the selected logical devices. This
register is read/write.
10.3.3 Chip ID Byte 1 (Index=20h, Default=86h)
This register is the Chip ID Byte 1 and is read only. Bits [7:0]=86h when read.
10.3.4 Chip ID Byte 2 (Index=21h, Default=73h)
This register is the Chip ID Byte 2 and for read only. Bits [7:0]=73h when read.
10.3.5 Chip Version (Index=22h, Default=01h)
This register is the Chip Version and for read only.
10.3.6 Clock Selection Register (Index=23h, Default=00h)
Bit
7-1 Reserved
0 CLKIN frequency.
1: 48 MHz.
0: 24 MHz.
Description
10.3.7 Software Suspend (Index=24h, Default=00h, MB PnP)
This register is the Software Suspend register. When bit 0 is set, IT8673F enters the “Software
Suspend” state. All the devices, except KBC, remain inactive until this bit is cleared or when the
wake-up event occurs. The wake-up event occurs at any transition on signals RI1# (pin 54) and Rl2#
(pin 56).
