0 Latched at reset. Not used on
the 362. 10 Pull-up with 1k0. Used to select
MAC with an RGMII interface.
1 Latched at reset. Not used on
the 362. 11 Pull-up via 1k0.
2 Latched at reset. Not used on
the 362. 12 UTOPIA or EMAC select.
Internal pull-down selects
EMAC.
3 Pull-up via 1k0. 13 Internal pull-up selects little
endian operation.
4 GP01 function. Connected to
CPLD via 1k0. A ‘0’ (default)
makes this an I/O pin. A ‘1’
enables the SYSCLK3 signal to
be output. 14 Internal pull-down selects 16 bit
HPI operation.
5 McBSP1 or GPIO selection.
Connected to the CPLD via 1k0.
A ‘1’ enables the McBSP
(default if GPIO).
15 Connected to CPLD via 1k0. A
‘0’ selects external clock for
EMIF. A ‘1’ selects SYSCLK3/8
as EMIF clock.
6 NC – PCI speed. 16 Internal pull-down. Set to ‘0’ for
DSPA. Set to ‘1’ for DSPB.
Together with EMIFA17-19, this
sets the boot mode.
7 NC – internal pull-down. 17 Internal pull-down.
8 NC – PCI auto-init. 18 Internal pull-down. Set to ‘1’ for
DSPA. Set to ‘0’ for DSPB.
9 Pull-up with 1k0. Used to select
MAC with an RGMII interface. 19 Internal pull-down.
Boot mode is the 4-bit value from EMIFA[19:16]. This is 0100 for DSPA (ROM boot) and
0001 for DSPB (HPI boot).
