TPU
A_TPUCH[0:15]
16
I/O
A_TPUCH[0:15] Provides TPU module A with 16 input/output programmable
timed events.
A_T2CLK / PCS5
1
I/O
A_T2CLK
This signal is used to clock or gate the timer count register
2 (TCR2) within the TPU module A. This signal is an
output-only in special test mode.
O
PCS5. This signal provides QSPI peripheral chip select
when the enhanced PCS mode is selected.
B_TPUCH[0:15]
16
I/O
B_TPUCH[0:15] Provides TPU module B with 16 input/output programmable
timed events.
B_T2CLK / PCS4
1
I/O
B_T2CLK
This signal is used to clock or gate the timer count register
2 (TCR2) within the TPU module B. This signal is an
output-only in special test mode.
O

when the enhanced PCS mode is selected.
Global Power
NVDDL
1
I
NVDDL
NVDDL. Noisy 2.6-V voltage supply input. This signal
supplies the final output stage of the 2.6-V pad output
drivers. The NVDDL and QVDDL supplies should be
connected to the same power supply in a user's system.
QVDDL
1
I
QVDDL
QVDDL. Quiet 2.6-V voltage supply input. This signal
supplies all pad logic and pre-driver circuitry, except for the
final output stage of the 2.6-V pad output drivers.
The NVDDL and QVDDL supplies should be connected to
the same power supply in a user's system.
VDDH
1
I
VDDH
VDDH. 5-V voltage supply input.
VDD
1
I
VDD
VDD. 2.6-V voltage supply input for internal logic.
KAPWR
1
I
KAPWR
Keep-Alive Power. 2.6-V voltage supply input for the
oscillator and keep-alive registers.
