Issue 1.1
2.1.4 STRAP REGISTER 3 INDEX 3CH (STRAP3)
Bits 7-0 of this register reflect the status of pins MD[47:40] respectively.
They are use by the chip as follows:
Bit 7-6, Reserved.
Bit 5, UART2 internal or external. This bit reflects the
value sampled on MD[45] pin
and controls the
UART2 I/F as follows:
Setting to ’0’, UART2 is external.
Setting to ’1’, UART2 is internal.
Bit 4, UART1 internal or external and additional TFT outputs. This bit reflects the
value sampled on
MD[44] pin
and controls the UART1 I/F and the additional TFT I/F as follows:
Setting to ’0’,UART1 is external and anadditional 6 TFT outputs (lowest bits - 2 red, 2 green
and 2 blue) are enabled.
Setting to ’1’, UART1 is internal.
Note that when strap option testbus enabled (see Section 2.1.3 Strap Register 2 bit 0) is driven to 1 it
takes priority over this strap which becomes meaningless.
Bit 3, Parallel Port internal or external. This bit reflects the
value sampled on MD[43] pin
and controls the
Parallel Port i/f as follows:
Setting to ’0’, the Parallel Port is external
Setting to ’1’, the Parallel Port is internal
Bit 2, KB/Mouse internal or external. This bit reflects the
value sampled on MD[42] pin
and controls the
KB/Mouse controller i/f as follows:
Setting to ’0’, the KB/Mouse controller is external
Setting to ’1’, the KB/Mouse controller is internal
Bit 1, Local Bus i/for ISA I/F. This bit reflects the
value sampled on MD[41] pin
and setswhether the Lo-
cal Bus i/f or the ISA i/f is available at the device i/f as follows:
Setting to ’0’, selectes the ISA I/F
Setting to ’1’, selectec the Local Bus I/F
Bit 0
PCMCIA i/f or the PCI i/f is available at the device i/f as follows:
Setting to ’0’, selects the PCI I/F
Setting to ’1’, selects the PCMCIA I/F
PCMCIA I/F or PCI I/F. This bit reflects the
value sampled on MD[40] pin
and sets whether the
This register defaults to the values sampled on MD[47:40] pins after reset.
