Description

EWAITN
I
External wait: Active low. This signal is asserted when an external I/O device or a
ROM/SRAM/FLASH bank needs more access cycles than those defined in the
corresponding control register.
81
RCSN[1]
O
ROM/SRAM/FLASH chip select: Active low. The KS8695X can access up to two
82
RCSN[0]
external ROM/SRAM/FLASH memory banks. The RCSN pins can be controlled to
map the CPU addresses into physical memory banks.
85
EROEN/
O/I
Normal mode: External I/O and ROM/SRAM/FLASH output enable: Active low.
WRSTPLS
When asserted, this signal controls the output enable port of the specified memory
device.
During reset: Watchdog timer reset polarity setting. WRSTPLS=0, Active low;
WRSTPLS = 1, active high. No default.
89
ERWEN0/
O
External I/O and ROM/SRAM/FLASH write byte enable: Active low. When asserted,
TESTACK
the ERWENx controls the byte write enable of the memory device (except SDRAM).
ARM CPU test signal (factory test signal).
88
ERWEN1/
O
External I/O and ROM/SRAM/FLASH write byte enable: Active low. When asserted,
TESTREQB
the ERWENx controls the byte write enable of the memory device (except SDRAM).
ARM CPU test signal (factory test signal).
87
ERWEN2/
O
External I/O and ROM/SRAM/FLASH write byte enable: Active low. When asserted,
TESTREQA
the ERWENx controls the byte write enable of the memory device except SDRAM).
ARM CPU test signal (factory test signal).
86
ERWEN3/
O
External I/O and ROM/SRAM/FLASH write byte enable. Active low. When asserted,
TICTESTENN
the ERWENx controls the byte write enable of the memory device (except SDRAM).
ARM CPU test signal (factory test signal).

WLED0/
O/I
Normal mode: WAN LED indicator 0: Programmable via WAN misc. Control register
B0SIZE0
bits [2:0].
000 = Speed; 001 = Link; 010 = Full/half duplex; 011 = Collision;
100 = TX/RX activity; 101 = Full-duplex collision; 110 = Link/Activity.
During reset: Bank 0 data access size. Bank 0 is used for the boot program.
B0SiZE[1:0] are used to specify the size of the bank 0 data bus width as follows:
‘01’ = one byte, ‘10’ = half-word, ‘11’ = one word, and ‘00’ = reserved.
118
WLED1/
O/I
Normal mode: WAN LED indicator 1: Programmable via WAN Misc. Control register
B0SIZE1
bits [6:4].
000 = Speed; 001 = Link; 010 = Full/half duplex; 011 = Collision;
100 = TX/RX activity; 101 = Full-duplex collision; 110 = Link/Activity.
During reset: Bank 0 data access size. Bank 0 is used for the boot program.
B0SIZE[1:0] are used to specify the size of the bank 0 data bus width as follows:
‘01’ = one byte, ‘10’ = half-word, ‘11’ = one word, and ‘00’ = reserved.
