Peripheral Pin Multiplexing (PPM) Module
SHORT_REG[SH_ET2]. ETRIG1 can be shorted to A_TPUCH15 and ETRIG2 can be shorted to
B_TPUCH15.
Since the ETRIG1 and ETRIG2 signals are shared with PCS6 and PCS7 respectively, the PPM shorting
will allow both ETRIG and PCS functions to be available. By setting up A_TPUCH15 and/or
B_TPUCH15 as output signals, enabling a short to ETRIG1 and/or ETRIG2 and sending a trigger signal
from the TPU channels, the QADC64E can be successfully triggered, leaving the ETRIG signals free to
be configured for PCS functions.
18.3.2.4
Each of the two TPU modules has an input clock, T2CLK. The A_T2CLK and B_T2CLK signals are
shared with PCS4 and PCS5 respectively. The T2CLK signals can be shorted internally by
SHORT_REG[SH_T2CLK] so that only one signal needs to be input to the device, leaving the other signal
free for PCS functionality.
18.3.3
The PPM module has six pads associated with it, four I/O pads PPM_RX[0:1] and PPM_TX[0:1] and two
clock outputs PPM_TCLK and PPM_TSYNC. All six PPM signals are multiplexed with MIOS signals. In
order to be able to access the PPM functions the signals must be configured appropriately. PPM pad control
is done in the PDMCR2 register.
As well as enabling signal functions, this register can configure the PPM pads for 2.6-V or 5-V operation.
