CONTROL BYTE SUBADDRESS 06
Table 18 Control bits for ppnctrl control via 5-bit DAC
Table 19 Control bits for ppnscl control via 5-bit DAC; note 1
Note
1. The currents of all DACs is controlled by reference current (IRREF). The given currents are valid at IRREF = 900 A.
8.1.10
CONTROL BYTE SUBADDRESS 07
Table 20 Control bits for porr
Note
1. When porr is set to logic 1 it ensures that the POR read bit is reset to logic 0. This way a reading of POR is always
at logic 1 with the occurrence of an actual power-on I2C-bus register reset and cannot accidentally be caused by
other I2C-bus control bits. Bit porr has no control function; it is an ‘unused’ bit dedicated by name to change the
I2C-bus register content from the POR state. Bit POR of the read byte is a wired NOR function that checks all
I2C-bus register bits: when the I2C-bus register contents equals the Power-on reset default state POR will read
logic 1, also when this state is set via the I2C-bus control. Because a setting of porr = 1 differs from the POR default
state it forces a reset to logic 0 of the POR bit independent of other bit settings.
