Peripheral Pin Multiplexing (PPM) Module

Freescale Semiconductor
TX_CONFIG_1 and TX_CONFIG_2 can only be written while PPM transmit mode is disabled
(PPMPCR[ENTX] = 0). While transmit is enabled these registers read as 0x00 and writing them will return
TEA (bus error access).
18.4.4
Receive Configuration Registers (RX_CONFIG_1 and
RX_CONFIG_2)
The two receive configuration registers control which internal modules will receive data from the PPM.
Each of the configuration registers contains eight separate 2-bit wide bit fields. Each of the 16 fields
controls a multiplexer that selects a 1-bit channel from the PPM data receive register to an internal module.
See
for more information on channel control and setting the channel values.
RX_CONFIG_1 and RX_CONFIG_2 can only be written while PPM receive mode is disabled
(PPMPCR[ENRX] = 0). While receive mode is enabled these registers read as 0x00 and writing them will
return TEA (bus error access).
