Functional Limitation of LIN-USART High-Pulse Output on SCK after Software Reset
Description
High-pulse will be output on SCK of LIN-USART (Local Interconnect Network - Universal Synchronous
Asynchronous Receiver Transmitter) after software reset in synchronous master mode. To avoid such extra pulse
on SCK, special care has to be taken when LIN-USART is used in synchronous master mode and the SCK mark
level are ‘0’.
Contact your local Cypress Sales Representative if you have questions.

Functional Limitation of LIN-USART
High-Pulse Output on SCK after
Software Reset
Root Cause
Problem Description
In synchronous master mode (mode 2 with SMR: SCKE=1) and with the SCK mark level set to ‘0’ (ESCR:
SCES=’1’), there will be a high-pulse on the SCK line after software reset of LIN-USART (writing ‘1’ to SMR:
UPCL).
CLK
SCK
DATA
UPCL
(Software Reset)
ST：Start Bit
SP：Stop Bit
ST
SP
Mark Level =
“L”
The connected slave device may consider this pulse on SCK line as a serial clock.
Cause of the problem
SCK signal in LIN-USART has initial value ‘high’. Therefore, in synchronous master mode and with the SCK mark
level are set to ‘0’ there will be a high-pulse on the SCK line with software reset of LIN-USART (SMR: UPCL=1).
Workaround
To avoid this problem, please apply either one of following countermeasures.
Countermeasure of non-using software reset (UPCL)
To avoid this problem, please do not perform software reset of LIN-USART (SMR.UPCL=1) when ESCR.SCES bit
is "1"(Serial clock mark level “L”) in synchronous mode (Mode2).
Countermeasure of using software reset (UPCL)
When performing software reset of LIN-USART (SMR:UPCL=1), extra high-pulse on SCK pin can be suppressed
by switching temporarily pin function from SCK to port output as follows.
< F

MC-8FX, F
2
MC-16LX and F
2
MC-16FX family case>
Set output data for the port function on the SCK pin to 0 by writing ‘0’ to the related PDR (port data register) bit
and enable port output function for SCK pin by writing ‘1’ to the related DDR (Data Direction register) bit.
Disable SCK output by writing ‘0’ to SMR:SCKE bit before performing software reset of LIN-USART by writing ‘1’
to SMR:UPCL. Then enable SCK output again by writing ‘1’ to SMR: SCKE bit.
<FR family case>
Set output data for the port function on the SCK pin to 0 by writing ‘0’ to the related PDR (port data register) bit
and enable port output function for SCK pin by writing ‘1’ to the related DDR (Data Direction register) bit.
Disable SCK output by writing ‘0’ to the related PFR (port function register) bit before performing software reset of
LIN-USART by writing ‘1’ to SMR:UPCL. Then enable SCK output again by writing ‘1’ to PFR register bit.
