2.13.2 Shift Out - T2 Control (101)
2.13.3
In this mode, the shift rate is controlled by T2 (as in mode 100). However, with each read or write
of the SR Counter is reset and eight bits are shifted onto the CB2 line. At the same time, eight shift
pulses are placed on the CB1 line to control shifting in external devices. After the eight shift pulses,
the shifting is disabled, IFR2 is set, and CB2 will remain at the last data level. See Figure 2-10.
In this mode, the shift rate is controlled by the system PHI2 clock. See Figure 2-11.
