DESCRIPTION
OUTPUTS
NEW
60
1
NEW: A HIGH on this pin indicates that an Instruction Fetch is in progress.
BOOT
61
1
BOOT: A HIGH on this pin indicates that Boot Memory is being accessed. This pin can be set or reset by accessing
bit 3 of the Configuration Register.
MR/W
63
1
MEMORY READ/WRITE: A LOW on this pin indicates that a Memory Write operation is in progress.
UDS
59
1
UPPER DATA SELECT: A HIGH on this pin indicates that the high byte of memory (MD15-MD08) is being
accessed.
LDS
58
1
LOWER DATA SELECT: A HIGH on this pin indicates that the low byte of memory (MD07-MD00) is being
accessed.
GIO
16
1
ASIC I/O: A LOW on this pin indicates that an ASIC Bus operation is in progress.
GR/W
15
1
ASIC READ/WRITE: A LOW on this pin indicates that an ASIC Bus Write operation is in progress.
PCLK
62
0
PROCESSOR CLOCK: Runs at half the frequency of ICLK. All processor cycles begin on the rising edge of PCLK.
Held low extra cycles when WAIT is asserted.
TCLK
2
0
TIMING CLOCK: Same frequency and phase as PCLK but continues running during Wait cycles.
INTA
3
0
INTERRUPT ACKNOWLEDGE: A HIGH on this pin indicates that an Interrupt Acknowledge cycle is in progress.

DESCRIPTION
INPUTS
WAIT
13
WAIT: A HIGH on this pin causes PCLK to be held LOW and the current cycle to be extended.
ICLK
14
INPUT CLOCK: Internally divided by 2 to generate all on-chip timing (CMOS input levels).
RESET
12
A HIGH level on this pin resets the RTX. Must be held high for at least 4 rising edges of ICLK plus 12 ICLK cycle
setup and hold times.
