PA6DDR
Pin function
Notes: 1. IRQ6-A input when the ITS6 bit in ITSR is 0.
The pin function is switched as shown below according to the combination of the operating
mode, bit EXPE, bits MSS and BIDE in SSCRH, bit SSUMS in SSCRL, and bits TE and RE
in SSER of SSU, bit A22E in PFCR1, bits SSI0S1 and SSI0S0 in PFCR5, bit PA6DDR, and
bit ITS6 in ITSR of the interrupt controller.
2. SSI0-B input when SSI0S1 and SSI0S0 = B'01 in PFCR5, and SSUMS, BIDE, MSS,
3. SSI0-B output when SSI0S1 and SSI0S0 = B'01 in PFCR5, and SSUMS, BIDE, MSS,
TE, and RE = B'001×1 or B'10××1.
TE, and RE = B'0001×.
