Description
Full Port Mode.The value of the FPM bit determines if the auxiliary output port uses the full MDO
port or a reduced MDO port to transmit messages.
0 A subset of MDO pins are used to transmit messages.
1 All MDO pins are used to transmit messages.
MCKO Clock Gating Control.This bit is used to enable or disable MCKO clock gating. If clock
gating is enabled, the MCKO clock is gated when the NPC is in enabled mode but not actively
transmitting messages on the auxiliary output port. When clock gating is disabled, MCKO is
allowed to run even if no auxiliary output port messages are being transmitted.
0 MCKO gating is disabled.
1 MCKO gating is enabled.
MCKO Enable. This bit enables the MCKO clock to run. When enabled, the frequency of MCKO
is determined by the MCKO_DIV field.
0 MCKO clock is driven to zero.
1 MCKO clock is enabled.
