Section 18 Pin Function Controller (PFC)
18.2 Notes on Usage
18.2.1 Restriction in Using
In the use of the pins listed in the following table, please set the data registers and also pin
function controller (i.e. in the use of the output functions EXCEPT the function 1, please DO NOT
change the initial value (= 0) in the data registers of that pins).
Table 18.7 Pins restricted in using in SH7619
Function 1

PD2 input/output (port)
PD4 input/output (port)
PD5 input/output (port)
Function 2
(Related Module)
IRQ2 input (INTC)
IRQ4 input (INTC)
IRQ5 input (INTC)

Function 4

TxD1 output (SCIF)
DREQ0 input (DMAC)
SCK1 input/output (SCIF) DACK0 output (DMAC)
TxD2 input/output (SCIF) DREQ1 input (DMAC)
18.2.2 Details of Restriction
For the logical specs of the output functions of the pins listed in the above table (i.e. logical sum of
the value of the data register), when the data register of the pins is set to '1', the output of the pins
will be FIXED to '1' (= High). For the initial value of that data register is '0', it DOES NOT cause
any problems in the use of NOT writing any data at all after power-on-reset. In addition, the
output is fixed to '1' (= High) in the use of writing '1' to the data register, it must be safe with the
sets that have already worked without any problems UNLESS change the value of PFC, whereas
input functions do work safety even in the function 1.
