Bit 7..6 | I_PRE1..I_PRE0 (Pre-charge current factor):
00 = 5% of value defined with ICH_SCL1, ICH_SCL0 01 = 10% of value defined with ICH_SCL1, ICH_SCL0 10 = 15% of value defined with ICH_SCL1, ICH_SCL0 11 = 20% of value defined with ICH_SCL1, ICH_SCL0 |
Bit 5..4 | ICH_SCL1..ICH_SCL0 (charge current scaling factor):
00 = 25% of value defined with ISET resistor; safety timer will time out at 2x SFTY_TMR[0,1] 01 = 50% of value defined with ISET resistor; safety timer runs at its nominal time defined in SFTY_TMR[0,1] 10 = 75% of value defined with ISET resistor; safety timer will time out at 0.66x SFTY_TMR[0,1] 11 = 100% of value defined with ISET resistor; safety timer will time out at 0.5x SFTY_TMR[0,1] |
Bit 3..2 | I_TERM1..I_TERM0 (termination current scaling factor):
00 = 5% of value defined with ICH_SCL1, ICH_SCL0 01 = 10% of value defined with ICH_SCL1, ICH_SCL0 10 = 15% of value defined with ICH_SCL1, ICH_SCL0 11 = 20% of value defined with ICH_SCL1, ICH_SCL0 |
