CHAPTER 1 OVERVIEW
73 INT2/SC1/PE2 F [INT2] Input of external interrupt request. This
input is used from time to time while the
corresponding external interrupt is enabled.
Therefore, it is needed to stop output by other
functions except when such output is performed
intentionally.
[SC1] UART1 clock I/O. Clock output can be used
when UART1 clock output is enabled.
[PE2] General-purpose I/O port. This function is
valid when UART1 clock output is disabled.
74 INT3/SC2/PE3 F [INT3] Input of external interrupt request. This
input is used from time to time while the
corresponding external interrupt is enabled.
Therefore, it is needed to stop output by other
functions except when such output is performed
intentionally.
[SC2] UART2 clock I/O. Clock output can be used
when UART2 clock output is enabled.
[PE3] General-purpose I/O port. This function is
valid when UART2 clock output is disabled.

76 DREQ0/PE4
DREQ1/PE5 F [DREQ0, 1] Input of DMA external transfer request.
This input is used from time to time when this pin is
selected for the DMAC transfer cause. Therefore, it
is needed to stop output by other functions except
when such output is performed intentionally.
[PE4, 5] General-purpose I/O ports
77 DACK0/PE6 F [DACK0] Output of DMAC external transfer
request acceptance (ch0). This function is valid
when the output of DMAC transfer request
acceptance is enabled.
[PE6] General-purpose I/O port. This function is
valid when the output of DMAC transfer request
acceptance or DACK0 output is disabled.
