= 01. See the bus timing diagrams.
RMODE2: In Hardware Mode (BIS[1:0] = 11), this pin selects the receive
side operating mode.
Chip Select/Remote Loopback Enable
CS
signal is used for both the parallel port and the serial port modes.
RLB: In Hardware Mode (BIS[1:0] = 11), when high, remote loopback is
enabled. This function is only valid when the transmit side and receive side
are in the same operating mode.
Address Latch Enable (Address Strobe)/Address Bus Bit 7/MCLK
Prescale Select 1
ALE (AS): In multiplexed bus operation (BIS[1:0] = 00), it serves to
demultiplex the bus on a positive-going edge.
A7: In nonmultiplexed bus operation (BIS[1:0] = 01), this pin serves as A[7].
MPS1: In Hardware Mode (BIS[1:0] = 11), MCLK prescale select, used to set
the prescale value for the PLL.
Write Input (Read/Write)/Transmit Mode Select 3
WR
TMODE3: In Hardware Mode, this pin selects the transmit-side operating
mode.
: This active-low signal must be low to read or write to the device. This
: In Processor Mode, this pin is the active-low write signal.
(
DS
): These pins are active-low signals. DS is active high when BIS[1:0]
