Description
SSU Module Standby
When this bit is 1, the SSU enters the module standby
state. In the module standby state, the SSU internal
registers other than SSCRL cannot be written to.
SSU Mode Select
Selects which combination of the serial data input pin and
serial data output pin is used.
For details, refer to section 16.4.3, Relationship between
Data Input/Output Pin and Shift Register.
0: Clocked synchronous communication mode
1: Four-line bus communication mode
Software reset
When this bit is set to 1, the SSU internal sequencer is
forcibly reset. Then this bit is automatically cleared. The
register value in the SSU is retained.
SSCK Pin Open-Drain Output Select
Selects whether the SSCK pin functions as CMOS output
or NMOS open-drain output.
0: CMOS output
1: NMOS open-drain output
Data input: SSI pin, Data output: SSO pin
When MSS = 1 and BIDE = 0 in SSCRH:
Data input: SSI pin, Data output: SSO pin
When MSS = 0 and BIDE = 0 in SSCRH:
Data input: SSO pin, Data output: SSI pin
When BIDE = 1 in SSCRH:
Data input and output: SSO pin
