RDY

O
CMOS
RDY: Ready/Data Acknowledge
In Multiplexed and Intel modes, a high level on this pin indicates that a read/write cycle is
completed. A low level on this pin indicates that wait state must be inserted.
In Motorola mode, a low level on this pin indicates that valid information on the data bus is
ready for a read operation or acknowledges the acceptance of the written data during a write
operation.
In EPROM and Serial modes, this pin should be connected to ground.
JTAG (per IEEE 1149.1)
TRST

I
pull-down
CMOS
TRST: JTAG Test Reset (Active Low)
A low signal on this pin resets the JTAG test port.
This pin should be connected to ground when JTAG is not used.
TMS
7
I
pull-up
CMOS
TMS: JTAG Test Mode Select
The signal on this pin controls the JTAG test performance and is sampled on the rising edge
of TCK.
TCK
9
I
pull-down
CMOS
TCK: JTAG Test Clock
The clock for the JTAG test is input on this pin. TDI and TMS are sampled on the rising edge
of TCK and TDO is updated on the falling edge of TCK.
If TCK is idle at a low level, all stored-state devices contained in the test logic will indefinitely
retain their state.
TDI
23
I
pull-up
CMOS
TDI: JTAG Test Data Input
The test data is input on this pin. It is clocked into the device on the rising edge of TCK.
TDO
21
O
CMOS
TDO: JTAG Test Data Output
The test data is output on this pin. It is clocked out of the device on the falling edge of TCK.
TDO pin outputs a high impedance signal except during the process of data scanning.
This pin can indicate the interrupt of T0 selected input clock fail, as determined by the
LOS_FLAG_ON_TDO bit (b6, 0BH). Refer to Chapter 3.8.1 Input Clock Validity for details.
