Circuit type
Function
[SI1] UART1 data input. Since this input is used whenever
UART1 is in input operation, the output by the other function must
F
remain off unless used intentionally.
[PF3] General-purpose I/O port
[SO1] UART1 data output. This function is enabled with the
UART1 data output flag set to “Enabled”.
F
[PF4] General-purpose I/O port. This function is enabled with the
UART1 data output flag set to “Disabled”.
[SC1] UART1 clock input/output. The clock output is enabled with
the UART1 clock output flag set to “Enabled”.
F
[PF5] General-purpose I/O port. This function is enabled with the
UART1 clock output flag set to “Disabled”.
[SI2] UART2 data input. Since this input is used whenever
UART2 is in input operation, the output by the other function must
F
remain off unless used intentionally.
[PF6] General-purpose I/O port
[SO2] UART2 data output. This function is enabled with the
UART2 data output flag set to “Enabled”.
F
[PF7] General-purpose I/O port. This function is enabled with the
UART2 data output flag set to “Disabled”.
[SC2] UART2 clock input/output. The clock output is enabled with
the UART2 clock output flag set to “Enabled”.
F
[PE0] General-purpose I/O port. This function is enabled with the
UART2 clock output flag set to “Disabled”.
[DREQ0] DMA external transfer request input (ch0) . Since this
input is used whenever the DMA external transfer request has
F
been selected as a DMA transfer trigger event, the output by the
other function must remain off unless used intentionally.
[PE1] General-purpose I/O port
[DACK0] DMAC external transfer request acknowledge output
(ch0) . This function is enabled with the DMAC transfer request ac-
knowledge output flag set to “Enabled”.
F
[PE2] General-purpose I/O port. This function is enabled with the
DMAC transfer request acknowledge output flag or DACK0 output
flag set to “Disabled”.
[EOP0] DMAC EOP output (ch0) . This function is enabled with
F
the EOP output flag set to “Enabled”.
[PE3] General-purpose I/O port
[DREQ1] DMA external transfer request input (ch1) . Since this
input is used whenever the DMA external transfer request has
F
been selected as a DMA transfer trigger event, the output by the
other function must remain off unless used intentionally.
[PE4] General-purpose I/O port
