Current Amps Limit Registers

Address:	^8B - Channel 1
	^8C - Channel 2
Access:	Read Only
Effective:	Instantly

These registers can be polled to view what the Amps limit is at the current time. This limit normally is the one that is preset by the user except when the controller is operating at high temperature, in which case the allowable current drops as temperature rises. See “Temperature-Based Current Limitation” on page 44.
