Revision A1
MXIE Monitor channel Transmit Interrupt Enable
Monitor interrupt status MDA, MAB generation is enabled (1) or masked (0).
MXC MX bit Control
Determines the value of the MX bit:
0: MX always 1.
1: MX internally controlled by the W6692 according to Monitor channel protocol.

MAC Monitor Transmit Channel Active (Read Only)
Data transmission is in progress in GCI mode Monitor channel.
0: the previous transmission has been terminated. Before starting a transmission, the
microprocessor should verify that the transmitter is inactive.
1: after having written data into the Monitor Transmit Channel (MOX) register, the microprocessor
sets this bit to 1.
This enables the MX bit to go active (0), indicating the presence of valid Monitor channel data
(contents of MOX) in the correspond frame.
TLP Test Loop
When set this bit to 1 both the DOUT and DIN lines are internally connected together, and the
constants T1 and T2 in D_TIMR are reduced. The GCI mode loop-back test function: DOUT is
internally connected with DIN, external input on DIN is ignored.
When TLP = 1 (GCI mode Test Loop-back Active):
T2 = 16348
CNT
DCL +T1, with T1 = 512
(VAL + 1)
DCL (here: DCL denotes the period
of the DCL clock.)
GRLP GCI Mode Remote Loop-back
Setting this bit to 1 activates the remote loop-back function. The 2B+D channels data received from
the GCI bus interface are looped to the transmitted channels.
