In emulation mode, the TPU executes microinstructions from MCU TPURAM exclusively. Access to the
TPURAM module through the IMB by a host is blocked, and the TPURAM module is dedicated for use
by the TPU. After reset, this bit can be written only once.
When the T2CG bit is set, the external TCR2 pin functions as a gate of the DIV8 clock (the TPU system
clock divided by 8). In this case, when the external TCR2 pin is low, the DIV8 clock is blocked, prevent-
ing it from incrementing TCR2. When the external TCR2 pin is high, TCR2 is incremented at the fre-
quency of the DIV8 clock. When T2CG is cleared, an external clock from the TCR2 pin, which has been
synchronized and fed through a digital filter, increments TCR2.
The IARB field is used to arbitrate between simultaneous interrupt requests of the same priority. Each
module that can generate interrupt requests must be assigned a unique, non-zero IARB field value. Re-
fer to the 3.8 Interrupts for more information.
The interrupt request level for all channels is specified by this 3-bit encoded field. Level seven for this
field indicates a nonmaskable interrupt; level zero indicates that all channel interrupts are disabled.
The TPU is assigned 16 unique interrupt vector numbers, one vector number for each channel. The
CIBV field specifies the most significant nibble of all 16 TPU channel interrupt vector numbers. The low-
er nibble of the TPU interrupt vector number is determined by the channel number on which the interrupt
occurs.
0 = TPU and TPURAM not in emulation mode
1 = TPU and TPURAM in emulation mode
0 = TCR2 pin used as clock source for TCR2
1 = TCR2 pin used as gate of DIV8 clock for TCR2
0 = TPU operating
1 = TPU stopped (STOP bit has been asserted)
0 = Assignable registers are unrestricted (FC2 is ignored)
1 = Assignable registers are restricted (FC2 is decoded)
0 = System clock/32 is input to TCR1 prescaler
1 = System clock/4 is input to TCR1 prescaler
