• ‘Resulting DCOIL’ is the (BIS state dependent) resulting coil drive setting. See Table 36-11 for
how this setting is derived from the value of the CONTROL register.
• RCIR denotes the setting of the corresponding bit in the CONTROL register.
Table 36-11 below shows the logic dependency of the resulting coil drive from the internal state of the SSD
block and from the setting of the different coil control bits in the CONTROL register:
