ARM9 microcontroller with CAN and LIN
8.7.3 MSCSS pin description
The pins of the LPC2917/19 MSCSS associated with the two ADC modules are described
in
in
. Pins directly connected to the four PWM modules are described in
: pins directly connected to the MSCSS timer 1 module are described in
.
8.7.4 MSCSS clock description
The MSCSS is clocked from a number of different sources:
(1) Timers:
c0 to c3 = capture in 0 to capture in 3
m0 to m3 = match out 0 to match out 3
(2) ADCs:
st0 to st3 = start 0 to start 3 inputs
s0 to s3 = sync_out 0 to sync_out 3
(3) PWMs:
c_i = carrier in
s_i = sync_in
s_o = sync_out
TE_i = trans_enable_in
TE_o = trans_enable_out
