Number of I2C bus samples taken after 1-to-0 transition on SDA (START
Condition)

Start condition hold time
Note:
1
833KHz is maximum for uPSD34xx devices.
Table 62 provides recommended settings for S1SETUP based on various combinations of
fOSC and fSCL. Note that the “Total Sample Period” times in Table 61 on page 126 are
typically slightly less than the minimum START condition hold time, tHLDSTA for a given I
2C
bus speed.
Important note: The SCL bit rate fSCL must first be determined by bits CR[2:0] in the SFR
S1CON before a value is chosen for SMPL_SET[6:0] in the SFR S1SETUP.
