I want to develop a test mpc8306 board , but i am confued with the number uart of mpc8306. the pin as below
signal package pin number
UART1_SOUT[1]/LSRCID4/LCS_B[4] C23
UART1_SIN[1]/LDVAL/LCS_B[5] F19
UART1_SOUT[2]/UART1_RTS_B1/LCS_B[6] D23
UART1_SIN[2]/UART1_CTS_B[1]/LCS_B[7] D22
USBDR_CLK/UART2_SIN[2]/UART2_CTS_B[1] Y9USBDR
USBDR_NXT/UART2_SIN[1]/QE_EXT_REQ_4 AC2
USBDR_PCTL[0]/UART2_SOUT[1]/
USBDR_PCTL[1]/UART2_SOUT[2]/
USBDR_TXDRXD[0]/UART1_SOUT[1]/
USBDR_TXDRXD[1]/UART1_SIN[1]/GPIO[33]/QE_TRB_I
USBDR_TXDRXD[2]/UART1_SOUT[2]/
USBDR_TXDRXD[3]/UART1_SIN[2]/
the material of mpc8306 says it has four uart port, but the signals show that it has six uart port, why ?

MPC8306 Reference Manual, Section 6.3.3 "Multisite Muxing":
UART1 interface is provided at two locations: LCS[4:7] and USB. If the user chooses LCS[4:7],
then UART1 cannot be used. Therefore, the same UART1 is also provided at another location, multiplexed
with USB.
UART1 multiplexed with LCS[4:7] has precedence over the one multiplexed with USB.
