BCLK Output Control
The BCLK output can be controlled with the PSTOP1 bit in SCKCR and the B3 bit in P5.DDR of corresponding P53.
When the PSTOP1 bit is cleared to 0, P53 functions as the BCLK output. When the PSTOP1 bit is set to 1, the BCLK
output stops at the end of the bus cycle and goes high. When the B3 bit in P5.DDR of P53 is cleared to 0, the BCLK
output is disabled and the pin functions as an input port.
Table 8.6 shows the BCLK pin state in each operating mode.
