• Manufacturer: Winbond Electronics

Specifications of W66910CD

• Lead Free Status / Rohs Status: Not Compliant

MDR0 Monitor channel 0 Data Receive
MER0 Monitor channel 0 End of Reception
MDA0 Monitor channel 0 Data Acknowledged
The remote end has acknowledged the Monitor byte being transmitted.
MAB0 Monitor channel 0 Data Abort
8.1.31 Monitor Channel 0 Control Register
Value after reset: 00H
MRIE0 Monitor Channel 0 Receive Interrupt Enable
MRC0 MR Bit Control
Determines the value of the MR bit:
0: MR bit always 1. In addition, the MDR0 interrupt is blocked, except for the first byte of a packet (if MRIE0=1).
1: MR internally controlled by the W66910 according to Monitor channel protocol. In addition, the MDR0 interrupt
is enabled for all received bytes according to the Monitor channel protocol (if MRIE0=1).
MXIE0 Monitor channel 0 Transmit Interrupt Enable
Monitor interrupt status MDA0, MAB0 generation is enabled (1) or masked (0).
MXC0 MX bit Control
0: MX always 1.
1: MX internally controlled by the W66910 according to Monitor channel protocol.
8.1.32 GCI Mode Control/Status Register
Value after reset: 00H
MAC0 Monitor Transmit Channel 0 Active (Read Only)
Data transmission is in progress in GCI mode Monitor channel 0.
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 0 (MO0X) 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.
Determines the value of the MX bit:
MAC0
Monitor channel interrupt status MDR0, MER0 generation is enabled (1) or masked (0).
