Output of the Bφ clock can be controlled by bits PSTOP1 and POSEL1 in SCKCR, and DDR for
the corresponding PA7 pin.
Clearing both bits PSTOP1 and POSEL1 to 0 enables the Bφ clock output on the PA7 pin. When
bit PSTOP1 is set to 1, the Bφ clock output stops at the end of the bus cycle, and the Bφ clock
output goes high. When DDR for the PA7 pin is cleared to 0, the Bφ clock output is disabled and
the pin becomes an input port.
Tables 20.3 shows the states of the Bφ pin in each processing state.
