Figure 9 SSC Timing Definition
• SSC Inactive Time ( CS_off )
The SSC inactive time defines the delay, before the TLE5010 can be selected again
after a transfer. The TLE5010 reacts only to one command after SSC inactive time.
Then the SSC Interface of the TLE5010 is disabled until the next SSC Inactive Time
is performed.
• DATA Write Time ( t_DATW )
During this time the TLE5010 changes the data line, thus the data are invalid.
The DATA Write Time values are defined without pull-up resistor.
• Pull-up Time Value ( t_PU )
The value in Table 13 "SSC Timing Specification" on Page 27 is estimated with
60 ns.
• Chip Select Off time ( t_CSOFF )
