SSCR2 is a register that enables/disables the open-drain outputs of the SSO, SSI, SSCK, and SCS
pins, selects the assert timing of the SCS pin, data output timing of the SSO pin, and set timing of
the TEND bit.

Description
Conflict/Incomplete Error
Indicates that a conflict error has occurred
when 0 is externally input to the SCS pin with SSUMS
= 0 (SSU mode) and MSS = 1 (master mode).
If the SCS pin level changes to 1 with SSUMS = 0 (SSU
mode) and MSS = 0 (slave mode), an incomplete error
occurs because it is determined that a master device
has terminated the transfer. Data reception does not
continue while the CE bit is set to 1. Serial transmission
also does not continue. Reset the SSU internal
sequencer by setting the SRES bit in SSCRL to 1
before resuming transfer after incomplete error.

TENDSTS
When a low level is input to the SCS pin in master
mode (the MSS bit in SSCRH is set to 1)
When the SCS pin is changed to 1 during transfer in
slave mode (the MSS bit in SSCRH is cleared to 0)
When writing 0 after reading CE = 1
(When the CPU is used to clear this flag by writing 0
while the corresponding interrupt is enabled, be
sure to read the flag after writing 0 to it.)
