• This bit selects the capture source for Input Capture Unit 1 and 5, and is used by
UART3-LIN-Operation
• Writing "0": The capture source is external.
• Writing "1": The capture source is UART3.
The IUCE3 bit exists only for MB90V390HA/MB90V390HB.
• This bit selects the capture source for Input Capture Unit 3, and is used by
UART2-LIN-Operation
• Writing "0": The capture source is external.
• Writing "1": The capture source is UART2.
For MB90394HA, MB90F394H(A), this bit is undefined.
• This bit is a valid edge indication bit for capture register IPCP1, IPCP3 and
IPCP5, to indicate that a rising or falling edge is detected
• "0": falling edge detected.
• "1": rising edge detected.
• This bit is read only.
Note:
The read value is meaningless, if EGm1, EGm0 = 00
• This bit is a valid edge indication bit for capture register IPCP0, IPCP2 and
IPCP4, to indicate that a rising of falling edge is detected
• "0": falling edge detected.
• "1": rising edge detected.
• This bit is read only.
Note:
The read value is meaningless, if EGn1, EGn0 = 00
