8.3  Resets and Low-Power Modes 

The external 

RST

 pin and the global reset bit in 

GL.CR1

 create an internal global reset signal. The global reset 

signal resets the status and control registers on the chip (except the 

GL.CR1.

 RST bit) to their default values and 

resets all the other flops to their reset values. The device should be reset after all power supplies, SYSCLKI, 
RX_CLK, and TX_CLK are stable. The processor bus output signals are also placed in high-impedance mode 
when the 

RST

 pin is active (low). The global reset bit (

GL.CR1.

 RST) stays set after a one is written to it, but is 

reset to zero when the external 

RST

 pin is active or when a zero is written to it. Allow 5ms after initiating a reset 

condition for the reset operation to complete. 

The Serial Interface reset bit in 

LI.RSTPD

 resets all the status and control registers on the Serial Interface to their 

default values, except for the 

LI.RSTPD.

RST bit. The Serial Interface includes the HDLC encoder/decoder, X86 

encoder and decoder and the corresponding serial port. The Serial Interface reset bit (

LI.RSTPD.

RST) stays set 

after a one is written to it, but is reset to zero when the global reset signal is active or when a zero is written to it. 

Table 8-2. Reset Functions

COMMENTS 

Hardware Device Reset 

RST

 Pin 

Transition to a logic 0 level resets the 
device. 

Hardware JTAG Reset 

JTRST

 Pin 

Resets the JTAG test port. 

Global Software Reset 

GL.CR1 

Writing to this bit resets the device. 

Serial interface Reset 

LI.RSTPD 

Writing to this bit resets a Serial 
Interface. 

Queue Pointer Reset 

GL.C1QPR 

Writing to this bit resets the Queue 
Pointers. 

There are several features in the DS33Z41 to reduce power consumption. The reset bit in the 

LI.RSTPD

 register 

minimizes power usage in the Serial Interface. Additionally, the 

RST

 pin or 

GL.CR1

.RST bit may be held in reset 

indefinitely to keep the device in a low-power mode. Note that exiting a reset condition requires re-initialization 
and configuration. For the lowest possible standby current, clocks may be externally gated.
