Serial Management Controllers (SMCs)
TIMEOUT Command. This transmitter command may be issued when the QUICC imple-
ments the monitor channel protocol. It is issued because the device is not responding or
because GCI A-bit errors are detected. When issued, the QUICC sends an abort request on
the E-bit.
7.11.14.4 SMC GCI MODE REGISTER (SMCMR). The operating mode of an SMC is
defined by the SMCMR. The SMCMR is a 16-bit, memory-mapped, read-write register. The
register is cleared at reset. The functions of bits 7–0 are common to each SMC protocol. The
functions of bits 15–8 vary according to the protocol selected by the SM bits.
Bit 15, 9, 7, 6—Reserved
CLEN—Character Length
ME—Monitor Enable
C#—SCIT Channel Number
SM—SMC Mode
DM—Diagnostic Mode
TEN—SMC Transmit Enable

These bits should be cleared by the user.
This value is used to define the total number of bits in the C/I and monitor channels of the
SCIT channel 0 or channel 1. CLEN ranges from 0 to 15 and specifies values from 1 to
16 bits. CLEN should be written with 13 for the SCIT channel 0 or GCI (8 data bits, plus
A and E bits, plus 4 C/I bits = 14 bits). CLEN should be written with 15 for the SCIT channel
1 (8 data, bits, plus A and E bits, plus 6 C/I bits = 16 bits).
0 = The SMC does not support the monitor channel.
1 = The SMC supports the monitor channel with either the transparent or monitor chan-
0 = SCIT channel 0
1 = SCIT channel 1 (required for Siemens ARCOFI and SGS S/T chips)
00 = GCI or SCIT support (required for SMC GCI or SCIT operation)
01 = Reserved
10 = UART
11 = Totally transparent operation
00 =Normal operation
01 =Local loopback mode
10 = Echo mode
11 = Reserved
0 = SMC transmitter disabled
1 = SMC transmitter enabled
