During hardware reset, the external ROM address pins ROM_ADDR[15:0] are configured as
inputs. On the negating edge of RESETn, the value on these pins is latched and stored. This
value is readable by the on-chip microcontroller (or an external microcontroller via the host
interface). Install a 10K pull-up resistor to indicate a ‘1’, otherwise a ‘0’ is indicated.

Description
HOST_ADDR(4:0)
USER_BITS(4:0)
ROM_ADDR(4:0)
If using 2-wire host protocol, these are bits 4:0 of the serial bus device address.
Otherwise, these settings are available for reading from a status register but are otherwise unused by the
gm2115/25. Used for “soft” configuration settings.
If using 2-wire host protocol, this is bit 5 of serial the bus device address.
Otherwise, program this bit to 0.
If using 2-wire host protocol, this is bit 6 of the serial bus device address.
Otherwise, program this bit to 0.
Program this bit to 0 for 2-wire host protocol operation.
Program this bit to 0 for 2-wire host protocol operation.
Determines the operating condition of the OCM after HW reset:
0 = OCM remains in reset until enabled by register bit.
1 = OCM becomes active after OCM_CLK is stable.
These settings are available for reading from a status register but are otherwise unused by the gm2115/25.
Selects reference clock source:
0 = XTAL and TCLK pins are connected to a crystal oscillator (see Figure 4).
1 = TCLK input is driven with a single-ended TTL/CMOS clock oscillator (see Figure 7).
Together with OCM_CONTROL register (0x22) bit 4, this bit selects internal/external ROM configuration.
0 = All 48K of ROM is internal.
1 = All 48K of ROM is in external ROM using ROM_ADDR15:0 address outputs if
register 0x22 bit 4 is 0. If register 0x22 bit 4 is 1, 0-32K ROM is internal, and
32K~48K ROM is external using ROM_ADDR13:0 address outputs.
