REGISTER SUMMARY

D-32
USER’S MANUAL
PSCK — Prescaler Clock
0 = System clock/32 is input to TCR1 prescaler
1 = System clock/4 is input to TCR1 prescaler
IARB — Interrupt Arbitration
Each module that generates interrupts must have an IARB value. IARB values are
used to arbitrate between interrupt requests of the same priority.
D.5.2 TCR
— Test Configuration Register
$YFFE02
The TCR is used for factory test of the MCU.
D.5.3 DSCR
— Development Support Control Register
$YFFE04
HOT4 — Hang on T4
0 = Exit wait on T4 state caused by assertion of HOT4
1 = Enter wait on T4 state
BLC — Branch Latch Control
0 = Latch conditions into branch condition register before exiting halted state.
1 = Do not latch conditions into branch condition register before exiting the halted
state or during the time-slot transition period.
CLKS — Stop Clocks (to TCRs)
0 = Do not stop TCRs.
1 = Stop TCRs during the halted state.
FRZ[1:0] — IMB FREEZE Response
The FRZ bits specify the TPU microengine response to the FREEZE signal.
CCL — Channel Conditions Latch
CCL controls the latching of channel conditions (MRL and TDL) when the CHAN reg-
ister is written.
0 = Only the pin state condition of the new channel is latched as a result of the write
CHAN register microinstruction.
1 = Pin state, MRL, and TDL conditions of the new channel are latched as a result
of a write CHAN register microinstruction.
