The device is reset when this bit is set

to â1â. The value of this bit is â0â when

read.

Must always be set to â0â

0 : BCLK is output

1 : BCLK is not output

(Pin is left floating)

Notes 1: Set bit 1 of the protect register (address 000A16) to â1â when writing new

values to this register.

2: If the VCC voltage is applied to the CNVSS, the value of this register when

reset is 0316. (PM00 and PM01 both are set to â1â.)

3: Valid in microprocessor and memory expansion modes.
