I/O Properties
Table 4-2 on page 32
summarizes the CL-PS6700 signals.
a
Synchronous signal indicates whether a signal is synchronous to PCLK.
b
These indicate the state of each output signal or the input pin during various states of the device.
For Reset,
Table 4-2 on page 32
indicates the state of each signal when RESET_L is asserted and power sta-
bilizes.

A
Normally operating output; can be high, low, or high-impedance.
PO
The state of an output during the deep Standby state is programmable, either low or high.
PI
Protected input; that is, the internal input buffer is de-coupled from the pin.
N
Normally operating input
