PRODUCTION DATA
Maximum Current Capabilities Register
This register indicates the maximum current capability for each voltage. The value is meaningful if the voltage support is set in the capabilities register (MMCHS_CAPA).
Initialization of this register (via a write access to this register) depends on the system capabilities. The host driver shall not modify this register after the initilaization.
This register is only reinitialized by a hard reset (via RESETN signal).
