LPC TO ISA BRIDGE SET
W83626F/W83626D
PRELIMINARY
Publication Release Date: Feb 2000
- 15 - Revision 0.50
CR15
(
GPIO0-GPIO7 Data Register,
Default 0x00)
The register is programmable when the bit 0 of CR10 is set to “ 1 “.
Bit [7..0] are corresponding with GPIO [7..0] .
If a port is programmed to be an output port, then its respective bit can be read/written.
If a port is programmed to be an input port, then its respective bit can only be read.
CR16
(
GPIO0-GPIO7 Inversion Register,
Default 0x00)
The register is programmable when the bit 0 of CR10 is set to “ 1 “.
Bit [7..0] are corresponding with GPIO [7..0] .
When set to a '1', the incoming/outgoing port value is inverted.
When set to a '0', the incoming/outgoing port value is the same as in data register.
CR17
(
Power LED & IRQIN Control Register,
Default 0x00)
Bit 7 -6:Reserved
Bit 5 -4: =00 Power LED pin is tri-stated.
=01 Power LED pin is driven low.
=10 Power LED pin is a 1Hz toggle pulse with 50 duty cycle.
=11 Power LED pin is a 1/4 Hz toggle pulse with 50 duty cycle.
Bit 3 - 0: These bits select IRQ resource for IRQIN. Four bits transfer the decimal value to octal
system. For example: Bit [3..0] = 1001b = 0x9h means IRQ 9 be selected.
Bit [3..0] = 1100b = 0xCh means IRQ12 be selected
CR20
(
Chip ID Register 1,
Default 0x62)
Bit 7 - 0: DEVIDB7 - DEBIDB0 --> Device ID Bit 7 - Bit 0 =
0x 62
(read only).
CR21
(
Chip ID Register 2 ,
Default 0x6x)
Bit 7 - 0: DEVREVB7 - DEBREVB0 --> Device Rev Bit 7 - Bit 0 =
0x61
(read only).
